Square Grippers-Counterbored
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.
Application Information
Square Grippers can be mounted against a step for positive resistance to rotation.
Installation
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.
