Square & Hex Bore Shaft Collars & Couplings

Our 1-Piece Clamp-Type Shaft Collars fit on standard hexagonal shafts.

Our hex bore shaft collars are generally in-stock for same-day shipment and our team is well-prepared to assist with any client question.

2-Piece Clamp-Type Shaft Collars can be completely disassembled and placed anywhere on a shaft.

Two-piece split clamp bore shaft collars are easy to completely disassemble. Afterward, they can be placed anywhere on a shaft. These collars are easy to adjust and boast high clamping power.

A mounting two-piece stackable collar helps mount square shafts or structural tubing to components. We supply these collars with a mounting screw and flats on both sides to ensure safe stacking. Customers can select from steel, stainless steel, or aluminum mounting two-piece stackable collars.

Each of our collars features two-piece construction. This ensures simple attachment to other components (or to each other).

The regular Stackable version has flats on two surfaces for stacking. The Stackable (Cap) version has a single flat to leave a finished outside surface when no further stacking is required.

Stafford’s exclusive Precision Sleeve Coupling features a solid center section that provides a close tolerance fit on ground shafting and a smooth bore that protects the shaft from damage. To assure precise shaft alignment, it maintains <.001″ TIR concentricity while in use. The two-piece coupling comes completely apart to allow the most convenient assembly and adjustment. It is precision machined, non-marring, easy to adjust, with high clamping power.

The Accu-Clamp™ design incorporates integral self-centering clamping collars at both ends.

Designed for aligned shafts, the 2-Piece Clamp-Type Hex Bore Coupling makes two shafts function as one, mating two shafts with zero backlash. This coupling comes completely apart to allow the most convenient assembly and adjustment.

This clamp-type coupling is precision machined for hexagonal shafts, non-marring, easy to adjust, includes a smooth bore that protects the shaft from damage, and has high clamping power.
