Screw Clamps

Hole-Mount Screw Clamps

Also known as press screws, mount these clamps through a drilled hole and turn the crank to move the jaw end of the screw in and out.

Screw Clamps

The spring-loaded tips on these clamps swivel in all directions to make maximum contact with angled and uneven workpieces.

Revolving Screw Clamps

When loosened, you can spin the body of this clamp around its mounting point for better access to the workpiece.

Quick-Clamping Coil-Threaded
Rods, Screws, and Nuts

Combine fast-threading components to build a clamping assembly.

Push/Pull Clamps

Push/Pull Toggle Clamps

Push or pull the plunger to hold your workpiece from the side.
