OK-Vise® Self-Adjustable Jaw Clamp

These clamps have a self-adjustable ball gripper screw inserted into a clamp jaw. The ball bearing at the end is made of steel and equipped with torsion protection, allowing the ball to self-adjust up to 9 degrees. This makes clamping irregular-shaped parts and castings more flexible.
