OMEGA‑screw clamp GMZ with tommy bar

Innovative OMEGA bend

The patented OMEGA bend gives you added safety. It means you lose even less clamping pressure, even when vibrations are present.

Maximum flexibility

The clamp forged from a single piece with moulded pressure plate is hardened, tempered and galvanised, making it highly durable and torsion-resistant. The clamps clamp resiliently and elastically.

Close flat clamping

The OMEGA bend allows you to place the clamp absolutely flat to the surface of the workpiece. This allows clamping right into the corners.

Pressure plate

For enhanced serviceability the pressure plate can be changed with no need for tools. It can be replaced very easily and quickly.
