What is the difference between screw clamps and one-handed clamps?

Screw clamps and one-handed clamps are among the most important clamping tools in the workshop. They are used to securely fix workpieces in place – whether for gluing, assembling, drilling or welding. Both types of clamps have their specific strengths and weaknesses, which can be decisive depending on the area of application. The tools are designed for professional craftsmen and demanding DIY enthusiasts, as well as anyone who needs high-quality clamping tools for their projects.

A major advantage of the screw clamp is the extremely high clamping force generated by the mechanical thread. Even large or stubborn workpieces can be securely fixed in place. Thanks to its precise adjustability, this clamp is particularly suitable for working with sensitive materials or for precise gluing. The main disadvantages are related to the speed of operation: the screw movement takes time and requires both hands, which is not always ideal for quick work.

One-handed clamps are the perfect solution when speed and ease of use are important. As the name suggests, they can be operated with just one hand. The mechanism works via a pump handle, which pulls the movable clamping arm continuously towards the workpiece. An inconspicuous button allows the clamp to be released immediately.

As different as the design and handling of screw clamps and one-handed clamps are, there are naturally also different advantages and disadvantages for these fixing tools. Basically, it can be said that the weakness of one is the strength of the other.

Advantages and disadvantages of screw clamps

• Higher clamping force
• Precise tension control
• Very solid, robust construction
• Long service life thanks to simple mechanics
• Two hands required for operation
• Slower handling
• Relatively heavy

Advantages and disadvantages of one-handed clamps

• Quick, one-handed operation
• Comparatively low weight
• Integrated spreading function
• Limited clamping and spreading force
• Not suitable for heavy-duty work
• Less robust construction

The right clamp for the right purpose

For anyone who values quality and reliability, both screw clamps and one-handed clamps offer a solid foundation for precise work. While screw clamps excel at power-intensive tasks and higher loads, one-handed clamps impress with their ease of use, speed and flexibility. Anyone who works regularly in a workshop should have both types of clamps in different sizes – so you are well equipped for any situation.

Screw clamps – powerful for maximum safety

High-quality screw clamps are made of tempered steel for the guide rail and cast iron for the clamping arms. This combination ensures extremely high load-bearing capacity and dimensional stability. The threaded spindle is usually made of hardened steel and has an ergonomic wooden or plastic handle. The fixed arm is connected directly to the rail, while the movable arm is adjusted via a trapezoidal threaded spindle and a rotary handle. Turning the handle generates a very finely adjustable, controlled clamping force, which allows workpieces to be pressed together very firmly and precisely. A ball-bearing head, to which the lower clamping jaw is attached, allows uneven objects to be securely fixed in place.

Our screw clamps are made of high-quality steel and grey cast iron and are available in various sizes. Popular variants include models with a clamping width of 150mm or 250mm and a clamping depth of 50mm. The larger version with a clamping width of 300mm and a clamping depth of 80mm allows for a deeper clamping surface and greater stability. Depending on the version, the pressure plates are made of steel or cast iron and are equipped with removable plastic protective caps to prevent damage to the workpiece.

Typical examples of use for screw clamps

When gluing a large dining table made of solid oak, every screw clamp counts. The heavy panels fit together perfectly and the pressure is distributed evenly. The thread of the clamp provides the necessary force to hold even stubborn parts together reliably. However, sensitive wood surfaces remain undamaged because the contact pressure can be precisely adjusted. Although both hands are required to position the clamp and the clamping process takes a little longer, when working with precision and high forces, stability is more important than speed – and this is exactly where screw clamps come into their own.

When welding a frame made of steel profiles, a screw clamp ensures precise alignment. The individual parts are positioned at exactly the right angle to each other without slipping. The thread allows controlled pressure to be applied to the joints, so that even small tolerances in material distortion can be compensated for very well. The heat generated during welding does not affect the fixed position of the components – the clamp remains in place. Even with heavier profiles, the fixation remains stable without warping. In such situations, it is not so much the speed of work that counts, but rather the accuracy and stability of the connection.

Our sizes for screw clamps

• 150mmx50mm Top pressure plate: 23mm x 30mm, bottom pressure plate: Ø 22mm
• 250mmx50mm Top pressure plate: 23mm x 30mm, bottom pressure plate: Ø 22mm
• 300mmx80mm Top pressure plate: 28mm x 40mm, bottom pressure plate: Ø 28mm

CONCLUSION:
Screw clamps are powerful and secure, making them particularly popular in metalworking, but also in carpentry and joinery. They are used for gluing furniture parts, frames or panels. They are indispensable in metalworking, for example when welding, fixing or aligning steel parts. The high clamping force ensures that workpieces do not slip, even under load.

One-handed clamping – quick clamping with just one hand

Good one-handed clamps usually consist of a reinforced plastic body (often polyamide PA6) and a steel rail. The clamping arms are also made of plastic, sometimes with separate pads made of a softer plastic to protect sensitive surfaces. The choice of material makes one-handed clamps lighter and more corrosion-resistant, but less resilient than screw clamps made of solid steel or cast iron. Their special pistol grip design makes them very comfortable to use, especially for assembly work or overhead work. They are lighter and more compact than screw clamps, but also less powerful. The maximum clamping force is limited due to their design. However, they are perfectly adequate for many common tasks such as fixing wooden panels, positioning components or quickly clamping workpieces.

Our shop offers one-handed clamps in several sizes, e.g. with a very small clamping width of 100mm and a clamping depth of 34mm – ideal for smaller jobs in model making or in confined working environments. For larger workpieces, variants with clamping widths of 150mm, 300mm or 450mm and a clamping depth of 64mm are available. The one-handed clamps also offer a spreading function that allows workpieces to be pushed apart – for example, when fitting components. Depending on the model, the spreading range is between 73 and 660mm.

Typical examples of applications for one-handed clamps

When installing an interior door, the craftsman uses the one-handed clamp to hold the frame precisely in position during assembly. The clamps fix the two frame elements securely and without slipping while the door opening is aligned and filled with foam. One-handed operation means that one hand is always free for the spirit level or assembly foam. The protective caps protect the frame from pressure marks. Every detail counts in this phase – a warped frame means a door that sticks later on. The one-handed clamp provides the necessary stability and saves valuable time. Once the foam has hardened, it can be removed at the push of a button.

When replacing an old window, the one-handed clamp secures the new window frame precisely in the reveal before it is screwed into the masonry. The frame sits loosely in the opening, but must be aligned exactly and secured against warping. With just a few simple steps, the one-handed clamp clamps the frame evenly without damaging the sensitive material. One hand is always free – to hold the spirit level or place the wedges while the other operates the clamp. The quick, secure fixing pays off, especially when working on a ladder or in cramped old buildings – clean installation without a second person.

When building a birdhouse, the one-handed clamp ensures stability when gluing the individual wooden parts together. The roof, floor and side walls are positioned at exactly the right angle and fixed in place in seconds. Additional clamps can be used to spread the clamp and prevent it from slipping inwards. The lightweight clamp does not get in the way while you work, and its plastic caps protect the soft wooden surfaces. Everything stays in place without slipping while the glue dries. Even children's hands can easily operate the mechanism – it is uncomplicated, quick and precise.

Our sizes for one-handed clamps

• 100x34mm Pressure plates: 17mm x 22mm, spread range: 73mm-183mm
• 150x63mm Pressure plates: 30mm x 40mm, spread range: 146mm-360mm

• 450x63mm Pressure plates: 30mm x 40mm, spread range: 146mm-660mm

CONCLUSION:
One-handed clamps are ideal for assembly work, craft projects or repairs. They enable quick fixing when drilling, screwing or gluing. Their one-handed operation allows you to work efficiently – especially on projects where you need to measure, align or hold something at the same time.

Which clamp size is the right one?

The correct size of the clamp is important to ensure that workpieces are held securely and without slipping. For screw clamps, the clamping width should be large enough to enclose the workpiece well, with some leeway for adjustment. For wide components or lower clamping points, models with a larger clamping width and clamping depth are ideal.

One-handed clamps are also available in various sizes – smaller versions are ideal for compact fixings during light work, while larger models offer more clamping force and hold larger workpieces securely in place. To use one-handed clamps for spreading, make sure that the possible spreading range of the clamp is greater than required for the task at hand – for example, when pushing frames apart or fitting components. Depending on the application, always choose the appropriate clamp length and function.

NOTE: In most cases, it is not a problem if the clamp is slightly larger, as even large clamps can still hold quite small objects securely in place. However, in confined spaces or when spreading, a clamp that is too large is less than ideal.

Tips for using fixing tools

• Protective caps or felt or wooden spacers should be used for sensitive surfaces
• The span should always be greater than the workpiece – ideally with some leeway
• Careful positioning prevents slipping during tightening – for optimal results
• Additional tightening with a wrench or lever may damage the thread or jaws
• Cleaning before or after use maintains the smooth running and service life of the tools
• For very large objects, the use of several fixing tools is highly recommended
• The combination of screw clamps and one-handed clamps makes alignment much easier

Care and storage of fixing tools

Both types of clamps should be cleaned regularly to remove chips, adhesive residue and dust. This will ensure that both mechanisms continue to operate smoothly in the long term. The threads of the screw clamps can be lubricated occasionally with a drop of oil. Plastic components of one-handed clamps should not be exposed to unnecessary UV radiation for long periods of time in order to delay ageing. The plastic caps should also be checked occasionally for damage and deposits to prevent them from leaving marks on soft or painted surfaces.

NOTE: Even though we rely on Högert screw clamps and one-handed clamps as tools for commercial use with the highest standards of quality and handling, which is also reflected in the selection of high-quality steels and metal alloys, we recommend storing them in a dry place to prevent possible corrosion of metal parts.
