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.

Side-actuated clamps tighten from the side of the clamp, gripping parts without a through hole in the top.

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.

Use these standard cam handles for most clamping applications. Push down on the handle and the head applies pressure to quickly draw two parts together for fast adjustments. Clamping distance is how far the handle will draw parts together when clamped.

Threaded-hole handles install on a threaded stud.

Threaded-stud handles mount into a threaded hole.

Aluminum handles have mild corrosion resistance, are lightweight, and are nonmagnetic.

Stainless steel handles have excellent corrosion resistance, making them the best choice for harsh environments. They also have good chemical resistance.

Also known as double cams, these complete cam handles have a durable, extra-large handle for clamping on fixture bases, plates, and workpieces. For fast adjustments, push down on the handle and the head applies pressure to quickly draw two parts together. All of these handles are made of steel with a black-oxide finish for mild rust resistance. Mount them into a threaded hole. Clamping distance is how far the handle will draw parts together when clamped.
