Proto J1218ASD 9/16" 12-Point ASD Combination Wrench

Product Description

FEATURES:
•Satin finish provides corrosion resistance and a slip resistant grip. •12 point box end allows for fine indexing, helping to improve speed and access. Fits 4, 6 and 12 point fasteners. •Fractional sizes 11/32" and smaller and sizes 1-5/16" and larger do not have the ASD feature. •Anti-Slip Design (ASD) open end. -Patented locking grooves help prevent the wrench from slipping off the fastener when turning. -The arched surfaces are designed to spread the contact forces over a greater area. -Loads are kept off the corners of the fastener which helps prevent fastener rounding. •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.
