Flat are hard, replaceable inserts used to provide additional wear resistance when installed in a fixture. The Delrin grippers shown here avoid marring finished workpieces. Made in USA.
These tapped Round 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. Tapped Round Grippers can also be installed in Gripper Swivel Pads and Gripper Swivel Contact Bolts.
