Product Information

ROEMHELD Contact Bolts (Radius)

Radius 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 radius-head version shown here provides firm contact even if the workpiece's surface is somewhat uneven. Available in thread sizes from 1/4-20 to 1"-8 (M5 to M48 in metric).
