Power Workholding Swivel Contact Bolts are for general-purpose use as contact points on Threaded-Body Push Clamps, Block Cylinders, Threaded Cylinders, and other workholding clamps. These hardened steel bolts protect the cylinder rod and provide a contact point to hold the workpiece securely. The swivel-head version distributes clamping force to prevent marring.
