Square Grippers

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 that 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. The hardened tool steel grippers shown here are the most economical and impact resistant. Made in USA.

Application Information

Square Grippers can be mounted against a step for positive resistance to rotation.

Installation

These tapped Square Grippers can be fastened from behind with a 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.
