Proto J7421MT Includes
- (1) 1/2″ DRIVE THIN WALL IMPACT SOCKET 21 MM – 12 POINT
Proto J7421MT Features
- Proto 12 Point Impact Sockets are ideal for use on stubborn or damaged fasteners, and also on fasteners made from soft materials.
- The TorquePlus design is a high performance drive configuration which allows for quick and easy socket engagement to the fastener flats, not the corners.
- The TorquePlus configuration employs a radius-corner design, shifting contact area and stress away from the fastener corners and distributing contact stresses over a large area of the socket, minimizing slippage.
- The TorquePlus internal design minimizes fastener rounding, helps to extend fastener life, and allows the user to more easily turn worn, rounded, or rusted fasteners.
- Socket size stamped on tool for easy identification.
- Side locking hole.
