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.

Low-Profile Fixture Clamps



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.
Blunt edge is less likely to mar your workpiece. Knife edge bites into your workpiece for faster and more aggressive machining.

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.

Machinable Dual-Clamping Fixture Clamps


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.

Inside Diameter Fixture Clamps


Secure a workpiece from the inside diameter, leaving the outside clear for machining. Machine these clamps to match the precise size and contours of your workpiece ID. Mount the clamp to your fixture with the included screws and place your workpiece over it. Turn the socket head cap screw to expand the clamp.
Top-actuated clamps tighten from the top of the clamp, so workpieces need a through hole.

Machine Table Clamps for Round Workpieces
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).
Use additional ANSI chain if your workpiece is larger than the maximum diameter of the clamps. You’ll also need links to connect each new section of chain.
