Inside Diameter Fixture Clamps


		Top Actuation

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 Actuation—Top-actuated clamps tighten from the top of the clamp, so workpieces need a through hole.
