  • Overmolded protection cap prevents dust and debris from jamming mechanism
  • Employs a pin system (versus screw) which connects the central block to the driving end and open end upgrading overall performance
  • Proto® 6 point 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
