Carr Lane Square Gripper, Steel, 1/2 x 1/2 Inch

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 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. Available in square sizes from 3/8 to 1" (10 to 25mm in metric). Made in USA
