Description

The 5/16″ x 5/16″ Aluminum Two-Piece Clamp – Precision Sleeve Square Bore Coupling is precision machined from lightweight aluminum and features a solid center section with a smooth square bore for a close-tolerance fit on square shafting. Its Accu-Clamp self-centering design provides high clamping power while maintaining less than 0.001″ TIR concentricity and axial runout for precise shaft alignment. The fully separable two-piece construction enables easy assembly and adjustment, while the non-marring smooth bore helps protect shafts from damage.
