3/8 x 3/8 Bore Sizes, 7/8 O.D, 1 3/8 Lg, One-Piece Steel w/o Keyway, Rigid Clamp Style Shaft Couplings (1 Each)
- The rigid couplings have high axial load and torque capacity.
- Recessed screw head provides an outside surface free of major projection for safety.
- Anodized aluminum provides corrosion resistance.
- The 6mm shaft couplers are widely applied to small CNC machines encoding and 3D printers Z shaft coupling, simplifies the debugging difficulty..
