Revolving Screw Clamps
When loosened, you can spin the body of this clamp around its mounting point for better access to the workpiece. Position over your workpiece and turn the handle to clamp down. Mount the clamp in a threaded hole or on a mounting base (sold separately).
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. Use mounting bases to attach screw clamps to flat surfaces. Their threaded portion is machined at a slightly downward angle so the clamp can get a strong grip on the workpiece. Length is measured from under the screw collar.
Optional extra-large steel tips offer more gripping strength. Optional nonmarring plastic tips minimize damage to workpieces.
