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.
