In addition to Bessey, you will also find our own sauter Cast Iron F-Clamps. We are convinced that no workshop should be without Cast Iron F-Clamps - see for yourself.

Cast Iron F-Clamps are characterized by a high degree of clamping force and robustness. When drilling or grinding small workpieces, the clamp can significantly increase the distance between hand and machine.

Applications of Cast Iron F-Clamps

The classic cast iron F-clamp is suitable for many clamping jobs due to their practical design and can be found in every workshop. We recommend the clamp for the following applications:

  • Bonding of glued wood panels, shelves, table tops, and much more
  • All bonding that requires a high contact pressure
  • Fixing of components

For clamping operations with high vibration levels, e.g. when used on the router table, cast iron F-clamps are not suitable. In this case we recommend practical lever clamps.

Components of Cast Iron F-clamps

The classic cast iron F-clamp is suitable for many clamping jobs due to their practical design and can be found in every workshop. The standard screw clamp consists of:

  • a rigid clamping bracket and
  • a mobile sliding clamp with spindle


The mobile clamp is moved along a rail, to set the desired clamping width. Due to the rigid clamping method, cast iron F-clamps are used for fastening wooden materials and for simple gluing work.

FAQ - Frequently asked questions about Cast Iron F-Clamps

How can I recognise a high-quality screw clamp?

A high-quality cast iron screw clamp can be recognised by its pleasant handling. Another indication of a high-quality clamp is that parts can be replaced. A high-quality cast iron clamp also transfers the built-up force optimally to the workpiece.

What is a cast iron screw clamp for?

The intended use of a cast iron screw clamp cannot be clearly limited. We recommend the cast iron clamp for every project where clamping, pressing or clamping is required.

What materials can I fix/clamp with a screw clamp?

The cast iron screw clamp can be used for a wide range of materials, such as wood, plastic and metal. A screw clamp should not be used when machining as the vibrations will loosen the clamp. We recommend lever clamps for use in the machine area.

What widths are recommened as a basic setup?

As a basic setup we recommend the widths: 150 mm 300 mm 600 mm 1,200 mm However, yit will depend on your project.
