Rigid Shaft Coupling: 5/8 in Bore Dia 1, 1/2 in Bore Dia 2, Round, One-Piece

One-piece rigid shaft couplings lock two shafts together when both shafts are inserted and all of the socket cap screws are torqued down to close the slotted clamp. This clamping action firmly grips both shafts without marring. The two shafts and coupling must be installed simultaneously to ensure proper alignment.
