Round Grippers-Counterbored
Serrated Round 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. These counterbored grippers are ideal for blind-hole installation and surface mounting. Made in USA.
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 (serration height is .062" on grippers with .125" x 90° serrations).
