Set-Screw Shaft Coupler (4mm Round Bore to 6mm Round Bore)


This set-screw coupler allows you to connect lengths of 4mm diameter round or D-shafting to 6mm diameter round or D-shafting. Each end of the coupler has an M5 set-screw with a nylon locking patch that secures the shaft in place and ensures the set-screw won't back out. Set-screw couplers are excellent in low-clearance applications.

As an added feature, this coupler has a built-in shim at each end. This allows the coupler to run against a bearing without contacting the outside race.
