Square Grippers are similar to Round Grippers, but their shape is useful when positive resistance to rotation is required (because they can be mounted against a step to prevent rotation). These serrated grippers are hard, replaceable inserts used to provide additional holding force and/or wear resistance when installed in a fixture. They are designed to slightly penetrate the workpiece to significantly increase gripping force, rather than relying on static friction alone. Made in USA.
Square Grippers can be mounted against a step for positive resistance to rotation.

Counterbored grippers are useful whenever fastening from behind or the side is not possible. Fasten with a standard socket-head cap screw. Grippers can be recess-mounted in a flat-bottom hole, or surface mounted to use as a rest pad. When grippers are installed in a hole, they should project 50 to 100% of serration height for maximum effectiveness.
