•Non-reflective ProtoBlack™ finish for use where non-plated products are required. •12 point box end allows for fine indexing, helping to improve speed and access. Fits 4, 6 and 12 point fasteners. •The box end is countersunk for easy application to the fastner. •15° angled offset box end helps keep shank clear of obstructions. •Inch sizes 1-5/16" and larger do not have ASD feature. •Box ends incorporate the TorquePlus™ system. •Proto® TorquePlus™ wrenches 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 wrench 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 box end, 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.
