Screw Clamps

The spring-loaded tips on these clamps swivel in all directions to make maximum contact with angled and uneven workpieces. Install by removing the tip, threading the screw through the mounting base’s hole, and reattaching the tip on the other side.

Extra-large steel tips offer more gripping strength. Nonmarring plastic tips minimize damage to workpieces.

Hole-Mount Adjustable-Travel Push/Pull Clamps

Drill a hole to mount these clamps through a surface and secure the mounting flange with screws. The plunger can be locked at any position along its travel. Push the plunger forward until it contacts the workpiece and then rotate the lever handle to clamp a workpiece from the side. The plunger is internally threaded to accommodate threaded holding screws and other threaded fixtures (not included).
