From facade rivets to sealing dowels - we deliver it

In addition to special screws and rivets for mounting façade cladding and balcony surrounds, we carry an extensive range of mounting materials for almost every application. Our wood screws are the right choice for screwing plastic panels together or to wood. Whether it is a countersunk screw or a pan head is not important in most cases, as long as the screw is not to be flush with the surface. Wood screws, however, are not only suitable for screwing directly into plastic or wood, but also for mounting objects with dowels in walls made of stone, concrete or clinker. We also offer the matching dowels in many different versions. From the most common diameters, to different lengths, to the type of construction for the various building materials. Even sustainably produced universal anchors, at least 50% of which are made from renewable raw materials, are part of our standard range.

In addition to the screws, dowels and rivets, which we offer in different sizes and designs from one piece at favourable graduated prices, we also stock practical FixTrainers from Fischer, which contain different dowels, screws or both, depending on the design. With these assortment boxes, the right installation material is always at hand for most installations in a well-sorted, clearly arranged transport box and can be easily refilled when needed.

However, our mounting materials include not only screws and dowels, but also our aluminium profiles for mounting façade cladding. In order to be able to mount these substructure profiles on the masonry, the matching steel wall anchors are available in our online shop. Depending on the distance between the construction and the wall, or the total weight after the façade panels have been installed, we stock the steel anchors in different lengths and diameters.

Stainless steel facade screws

For the installation of facade cladding with our HPL panels, we offer high-quality facade screws made of stainless steel. These are optionally available with or without scratch-resistant head lacquering at very favourable graduated prices, starting at just one screw. The lacquered screws are precisely matched to our HPL panels in RAL, so that the colour and gloss match the corresponding façade panel. The weatherproof screws are equally suitable for indoor and outdoor use and can also be used in damp rooms.

The screws with a coarse thread of 5.5x35mm are suitable for a substructure made of wood, but can also be used for screwing façade panels directly onto the wall - provided an appropriate anchor is used. However, the wood screws cannot be used for a tubular steel frame or a metal construction. For this purpose, we offer the appropriate screws with metric thread and self-locking cap nut in colour or bright in the category balcony screws.

Facade rivets in high variety

Blind rivets are an excellent method of joining parts permanently and securely together and have the advantage that, in contrast to gluing, the joint can be released again without great effort. Joining by riveting is one of the non-self-releasing cold joining methods. This means that a rivet, unlike screws, does not loosen by itself and can only be loosened again by drilling or chiseling. Rivets are available in countless designs and materials with different diameters and clamping ranges, but have the disadvantage that they are generally more suitable for thin-walled panels, such as our HPL or aluminium composite panels or stainless steel sheets.

Our facade rivets have the decisive advantage that the joining can be produced very quickly, without hardening of an adhesive. The joint is made from one side. The opposite side can be hidden or inaccessible. This is where blind rivets get their name from. Blind - i.e. invisible - riveting from one side.

In our online shop we not only offer you blind rivets in the most common sizes at very reasonable prices, but also the matching drills and tools.

Balcony screws with metric thread

Balcony screws are mainly used for the installation of balcony cladding with HPL panels. On the one hand, the screws owe their name to this application and on the other hand, this is also the reason why our head-lacquered screws have been exactly matched to our HPL panel in RAL in terms of colour tone and gloss level.

The name balcony screws may be a little misleading, however, because the screws can be used in a variety of ways, so that their use is not limited to the installation of balcony privacy panels. Similar to façade screws, the usability of balcony screws depends on the type of substructure. Facade screws are very suitable for a construction made of wood, but not for substructures made of metal, so our balcony screws with metric thread are the better choice here. We not only offer these in different colours, but also with different clamping ranges, which are based on the thickness of the cladding panel and the thickness of the supporting structure.

Wood screws in the highest variety

Wood screws suggest that they are suitable for fastening by screwing into boards and beams of any kind of wood. This is true, but wood screws are much more versatile than the name suggests, because regardless of whether they are countersunk or pan-head screws, wood screws are the perfect choice for fastening with dowels in walls made of concrete, solid or hollow stone and can also be used to screw plastic panels together.

In our online shop we offer wood screws in different lengths and thicknesses. Optionally with full thread or partial thread. In addition, we offer screws with countersunk heads for a flush screw connection of the attachment part. Countersunk screws are, for example, perfectly suited for erecting substructures made of wood that are later to be clad with facade panels outdoors or with plasterboard indoors. Our range also includes screws with a lens head, which are very suitable for fastening aluminium profiles, provided that a flush screw connection is not absolutely necessary. Lens head screws are particularly suitable for mounting wall and ceiling lights, shelves, cabinets and are always recommended if a washer is to be used between the attachment part and the screw head.

The right anchor for every wall

Not all walls are the same and therefore not all anchors are the same. Depending on the building material the wall is made of, it is advisable to use the appropriate dowel in order to achieve maximum safety with regard to the load-bearing capacity of the fastening. For this reason, we carry a whole range of different types of anchors in our online shop, from the all-purpose anchor, which is particularly suitable if the building material of the wall is unknown, to the conventional expansion anchor, which ensures the best possible hold in concrete and solid stone. In addition, we also offer anchors that are especially suitable for wet rooms and have a sealing effect without any additional sealants. Even in terms of sustainability, we have anchors in our range that are made from at least 50% renewable raw materials.

Like our screws, we offer the dowels in the most common diameters and various lengths at favourable prices, depending on the type.

Steel anchor for heavy loads

For installations on concrete that are subject to particularly high loads, steel anchors, often also referred to as impact bolts or wall anchors, are the perfect choice. They provide a permanent, secure hold and are particularly suitable for the floor fastening of high shelves, the assembly of metal cable platforms or our substructure profiles for heavy façade panels. Depending on the total load, the required driving depth or the necessary thread length, we offer steel anchors in diameters from 8mm to 12mm, as well as different lengths.

Substructure profiles made of anodised aluminium

Substructure profiles are used for the simple and quick installation of façade cladding that is to be implemented using riveted joints. A distinction is made between Z profiles for mounting one panel and omega profiles for mounting two adjacent panels. The profiles are made of high-quality, solid aluminium and anodised for the best possible protection against corrosion.

For maximum flexibility during installation, our aluminium profiles are not pre-drilled. This means that both the mounting points of the profiles to the masonry and the fixings for mounting the panels can be freely defined. However, this also means that the holes in the profiles must be drilled for this purpose. We carry suitable HSS drill bits, both for steel anchors and for mounting the façade panels with façade rivets, in the category Drills and bits.

High quality wall brackets for signs

Spacers for mounting pictures, signs, information boards and company signs, are a visually appealing alternative to mounting our plastic panel blanks on the wall with conventional screws. In our category of spacers & clamps, you will find a selection of high-quality wall brackets made of stainless steel with a gossamer-finished brushed surface and faceted cover cap in various designs. We offer you the solidly manufactured wall holders in various diameters and with different wall distances. In addition, we also offer the most common sizes with a flatter cover cap and locking screw, which makes it more difficult to remove the holders and signs.

All spacers in our online shop can be ordered from as little as one piece and can be delivered at short notice at any time thanks to extensive stock-keeping as a standard range. If you need spacers in other designs, for example with a higher wall distance, we are able to call them up from the manufacturer within a few days. The same also applies to spacers in polished or satin finish, or wall spacers made of other materials such as brass or aluminium.

Other fastening systems such as clamp holders for signs, rope fastenings for hanging signage and signposts, can also be obtained from the manufacturer at short notice on request.

The application determines the mounting material

How do you determine the right fixing solution?

The suitable fastening solution depends on what is to be fastened and on which material the installation is made. Not every anchor is equally suitable for every building material and the choice of screw also depends on a number of factors, such as the mounting weight and the number of fixings. In addition, not all screws are suitable for all anchors, because screws that are too small may cause the anchor not to spread sufficiently and thus have no or too little hold in the drill hole.

While small dowels with a diameter of 5mm or 6mm in combination with short screws are sufficient for mounting wall and ceiling lamps, as well as picture frames, wall clocks or whiteboards made of our white plastic panels, the load-bearing capacity is no longer sufficient for wall cupboards in the living room or kitchen, so that as a rule dowels with an 8mm or 10mm diameter have to be used here. Furthermore, it is of great importance what material the wall or ceiling is made of, because for each material there are wall plugs that are specially adapted to the properties in order to guarantee the best possible hold. For plasterboard, special plugs with a very coarse thread are available that are screwed into the plasterboard. For sand-lime bricks or hollow bricks, universal dowels that contract are more suitable than conventional expansion dowels, which, on the other hand, have a very good hold in solid building materials such as concrete or clinker.

Factors for choosing the right mounting material

  • The total weight (plus weight at maximum load, if applicable) of the object to be assembled
  • Tensile loads (e.g. pull-outs, drawers, cupboard doors) acting on the fixings
  • The material thickness and size (effective bearing surface) of the mounting surface
  • The material (e.g. wood, concrete, plasterboard, etc.) on which the installation is to be carried out
  • The condition and load-bearing capacity of the surface on which the installation is to be carried out
  • Manufacturers' specifications regarding the number and position of fixings
  • Demands on corrosion, weather and moisture resistance of the mounting material
  • Demands on the visual effect (colour, concealed mounting with countersunk screws, etc.)
  • Legal regulations, ordinances and standards (e.g. ETA approvals, material specifications)

NOTE: manufacturer's installation instructions usually provide sufficient information on the selection of suitable installation material. This information should always be observed and never undercut. In individual cases, however, it may make sense to choose a different fastening solution, for example, if conventional expansion anchors were included with the add-on part, which usually do not guarantee sufficient hold when mounting in sand-lime bricks, hollow bricks or plasterboard.

How do you determine the load capacity of the mounting material?

Before starting to install façade cladding, a cable tray or hanging cabinets, a number of factors that affect the load-bearing capacity of the mounting material must be taken into account in order to determine the appropriate fixing solution.

The texture and material of the wall and ceiling are of great importance

First and foremost, the load-bearing capacity of the wall or ceiling is of utmost importance and must be able to withstand the load, regardless of the installation material. As a rule, the more porous or unstable the building material, the lower the maximum load-bearing capacity. It therefore makes sense to determine the material of the wall in advance. Concrete, solid brick or solid sand-lime brick have the highest load-bearing capacity. Perforated lime sand bricks or gypsum fibre boards are also very good prerequisites for high load-bearing capacities, provided that suitable installation material is used. Hollow bricks, aerated concrete, gas concrete or plasterboard, on the other hand, do not have a high resistance to high tensile forces, so special attention should be paid to the right choice and number of fasteners. The situation is similar when mounting on wood. Here, solid hardwood withstands higher loads than softer types of wood or OBS boards.

The right mounting material is decisive for the lasting success of a fastener

Basically, the larger and longer a screw, the higher the load-bearing capacity of an individual fastening. However, this statement should be treated with caution, because the material of the screw also contributes to how resistant it is to tensile and transverse forces. Furthermore, it is also decisive whether the screw is screwed directly into the material, for example into a wooden board, a beam or a plasterboard, or whether the screw is screwed into a dowel. In addition, the thickness of the material into which the screw is screwed sometimes has a significant effect on the load-bearing capacity. A wooden panel with a nominal thickness of 8 mm is therefore considerably less resilient than a cladding made of 19 mm thick solid wood boards. Especially with smaller material thicknesses, it should be noted that wood screws with a full thread are the better choice.

If anchors are used, it can be of great importance that the anchor is adapted to the material and the nature of the wall. Rimless expansion anchors, for example, have a very good load-bearing capacity when used in concrete or solid stone. However, this anchor is rather unsuitable for hollow bricks, so that a universal anchor or an expansion anchor with multiple expansion and edge is usually the better choice here. For gas concrete, aerated concrete or gypsum plasterboard, on the other hand, separate anchor variants are available that are specially adapted to the respective materials with coarse threads. In addition, there are countless other anchor variants for special areas of application, such as cavity anchors made of metal, anchors for threaded screws, spring-loaded anchors with threaded rods or hooks, insulation anchors, and many more.

When installing with dowels and screws, in addition to choosing the right dowel for the material and the size of the dowel, it is important to use the right screws. Screws that are too short or have too small a diameter mean that the anchor does not achieve sufficient expansion and thus the load-bearing capacity is significantly reduced. Screws that are too large, on the other hand, can damage the anchor or the drill hole to such an extent that the load-bearing capacity can no longer be adequately guaranteed. The forestry formula is that the screw diameter should be one to two millimetres smaller than the diameter of the anchor. The length of the screw, on the other hand, should be longer than the anchor. Simplified, the screw length should be chosen in such a way that it corresponds to the length of the anchor plus the diameter of the screw. The mounting distance of the object to be mounted, as well as the insertion depth of the anchor, must be added to the screw length.

Multiple attachment points distribute the load and thus increase the total load capacity.

The load acting on a fastening is divided into three different main types. The tensile force, the transverse force and the oblique force. With tensile force, the force acts against the direction in which the anchor or screw is inserted. A very good example of tensile force is the ceiling mounting of a luminaire, which acts on the fixing with the weight of the luminaire. The shear force is the load acting at right angles to the direction of the fixing. When mounting a very flat wall lamp, the weight of the lamp acts as a transverse force on the fixture, to remain with the example of a luminaire mounting. The oblique force, on the other hand, is a mixed form of the two loads mentioned, which is always present when the weight acts on the fixture in both directions. A very good example is a wall shelf. Due to the weight of the shelf itself, there is always a transverse force. The further the wall shelf extends away from the wall, the higher the tensile force on the fastening, which is usually higher than the transverse force for a simple shelf. If the shelf is loaded with objects, the total weight and thus the transverse force as well as the tensile force increases. The further away these objects are placed on the shelf from the wall, the more pronounced the effect of this oblique force on the fixture, even though the total weight of the load has not changed. However, this load acts neither purely as a tensile force nor as a transverse force, but obliquely at a certain angle on the mounting point.

If you use a dowel with a diameter of 8mm and a length of 40mm in combination with a wood screw of size 6x60mm to mount a shelf in a concrete wall, a fastening point would have a maximum load of approx. 60kg, which results from the prevailing tensile force, shear force or oblique force. This value can be increased by bolting the shelf to the wall at two, three or more points to prevent it from falling due to excessive load. It is important to note that not only the weight or load of the shelf itself is decisive, but also the objects on the shelf and where they are positioned must be added to the load.

Factors that influence the load-bearing capacity of the mounting material

  • The nature of the material on which the assembly is to be carried out
  • The load-bearing capacity of a particular type of anchor on the material
  • The length and diameter of the anchor type used
  • The length and diameter of the screw used
  • The expected tensile force, shear force as well as oblique force
  • The total number and distribution of fixings of the assembly
  • The precision with which the necessary hole drillings are carried out
  • Consideration of the additional weight load due to loading

NOTE: The maximum load capacity sometimes varies significantly depending on the screw-dowel combination. For more information on the possible load capacities of a particular anchor, please refer to the respective product description.

How do you recycle assembly materials?

Mounting materials are available in countless designs and are made of just as many materials. Screws are usually made of metal and anchors are usually made of plastic. But not all screws are the same, and the alloys sometimes differ quite significantly. Most screws are made of steel or stainless steel, which can be recycled very well by melting them down to make new screws, washers or even tools. But there are also screws made of aluminium. These, just like our facade rivets, are also very well suited for raw material recycling. It makes perfect sense to separate aluminium from steel and to maintain maximum purity when recycling the metals. Collected in appropriate quantities, many metal processing companies are interested in the recycled material and sometimes pay a few euros, depending on the weight.

With plastic dowels it is much more complicated, because not all dowels are made of the same plastic and some dowels even consist of different components, so that recycling is usually uneconomical due to the mixed plastics. Nevertheless, dowels should be disposed of in the recycling bin, unless they are extremely contaminated (e.g. wall paint, wallpaper residues, gypsum plaster adhesions, etc.), because the plastic waste collected here is separated by special processes in recycling plants to ensure that it is as pure as possible. For all plastics for which a specific classification is not possible, thermal recycling is used, as would be the case if the dowels were disposed of via the residual waste bin.
