Fixture Clamps
Hold a workpiece securely from the side with minimal contact, leaving more of the workpiece free for machining. Thread the clamp into a tapped hole and give the center screw a half turn for quick clamping.

Fixture Clamps for Castings and Rough Parts
Unlike the smooth and flat edges of standard fixture clamps, these clamps have ridges that bite into parts, making them good for gripping castings and rough-cut stock. They hold workpieces securely from the side with minimal contact, leaving more of the surface free for machining. Thread the clamp into a tapped hole and give the center screw a half turn for quick clamping.

Dual-Clamping Fixture Clamps
Set one of these clamps between two workpieces in a fixture and tighten the screw to push the clamp's sides out for a secure hold. The minimal contact leaves more of the workpieces free for machining.

Inside Diameter Fixture Clamps for Castings and Rough Parts
These clamps wedge against the workpiece ID to grip cast, unfinished, or uneven parts, leaving the outside clear for machining. Do not use these clamps on smooth or finished ID’s because they will leave a mark. The clamp’s screw tightens from the top of the clamp, so workpieces require a through hole. Thread the clamp into a tapped hole in your fixture and place your workpiece over it. Reach through the hole to turn the screw, expanding the clamp.
