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.
