Install these clamps into a slot in your fixture to grip at the bottom of workpiece edges, giving the cutting tool maximum access to your workpiece. Thread the clamp into a tapped hole and give the center screw a half turn for quick clamping.

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.

Machine these fixture clamps to match the contours of your workpieces for a stronger grip. Place the clamp between the two workpieces in a fixture and tighten the screw to extend the sides of the clamp, creating a secure hold against both workpieces. Minimal contact with the workpiece leaves more of its surface accessible for machining. Each clamp comes with a locking plate to keep the clamp rigid while machining it to fit your application.

Secure large, round parts for machining. Often paired with V-blocks, these clamps come with five lengths of chain that you can combine to fit a variety of workpieces. Join them with the included connecting links. These clamps also come with nonmarring pads, which snap into the chain to keep it from damaging your workpiece. One end of these clamps has a cam-locking hook to secure the chain to the table and lock it around the workpiece. The other adjusts the tension, pulling the chain tight for a firm hold. Mount these clamps into slot nuts or fixture plates with socket head cap screws (not included).
