This set-screw coupler allows you to connect lengths of 5/16" diameter round shafting to 3/8" diameter round 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.
The set-screw included with this product features a nylon patch: a blue dollop of thread-locking magic that ensures extraordinary resistance to loosening from vibration!
