The patented GearWrench Ratcheting Wrench needs as little as 5º of movement to turn a fastener. Small ratcheting box end design allows access to tight spots where a ratchet and socket or a conventional ratcheting box end will not fit. The GearWrench will move a fastener along any length threaded rod without ever having to remove the wrench from the fastener. SurfaceDrive box end virtually eliminates the rounding of fasteners.
