CARATTERISTICHE: Square Grippers are similar to Round Grippers, but their shape is useful when positive resistance to rotation is required (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. The counterbored version is ideal for blind-hole installations.
MISURE: Counterbored Square Grippers are available in the following square sizes – see Dimensions page for part numbers:| | 1/2" | | 12mm | | | 3/4" | | 20mm | | | 1" | | 25mm |
INSTALLAZIONE: 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 1.6mm on grippers with 3.2mm x 90° serrations).
MATERIALE: M-2 tool steel, heat treated Rc 60-62, black oxide finish. |
