Clamping bolts are the central clamping elements used to securely fix squares, stops, and other accessories onto welding tables or to connect tool components. Their effortless and quick handling, even without the need for additional tools, ensures efficient and intuitive operation.
Optimal grip ergonomics
Threaded Handwheel with internal hexagon socket
Quick clamping and releasing by hand or with a hex wrench
For maximum strength the main body is manufactured from high-alloyed hardened steel
Wide range of different bolts for every application
Easy replacement and cleaning of the balls
Reliable and powerful fixation of components
Bolts without O-ring slot enable easy, precise fastening in aluminum profiles without the risk of tilting.
Large balls protect the chamfer of the boreholes due to low surface pressure
Support is provided by just 3 balls, ensuring optimal force distribution according to the trihedral principle
The fourth ball in the center minimizes internal friction and increases the torque of the handwheel
Fold-out elements made of through-hardened tool steel
flat interlocking and even force distribution
developed for aluminum and other soft materials
O-ring made of heat resistant and heavy-duty material
