Shaft Collars Set Screw Two-Piece

Black Oxide Shaft Collars Set Screw Two-Piece 
Tighten the set screws to bite into an unhardened shaft for a secure hold. The two-piece design allows you to install these collars anywhere on a shaft without removing components or having access to the ends of the shaft. Clamping screws provide extra grip. Collars are black-oxide steel, which offers some corrosion resistance.
