The 9/16″ x 9/16″ Stainless Steel (316/316L) Two-Piece Square Bore Clamp Coupling is designed to securely connect two aligned square shafts, allowing them to function as a single unit with zero backlash for precise torque transmission. Its two-piece clamp design enables convenient assembly, adjustment, and maintenance, while the precision-machined 316/316L stainless steel construction provides excellent corrosion resistance. The smooth square bore protects shaft surfaces from damage, and the non-marring clamp mechanism delivers high clamping force for a secure and reliable connection. Stocked in: 316 stainless
