Cam Handles

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.

Heavy Duty Cam Handles

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.

Expanding Cam Handles for Unthreaded Holes

Use these handles to keep holes aligned or lift several sheets of thin material. They have a plug that expands to grip the edges inside holes. They are not suitable for permanent installation—use only for temporary mounting. Made of plastic, all of these handles resist oil, grease, and solvents.
