J1242

Overview

• 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
• Arched surfaces are designed to spread the contact forces over a greater area, which means loads are kept off the corners of the fastener helping prevent fastener rounding
• Box ends incorporate the TorquePlus™ system
• 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
