Proto J1236M Combination Wrench Spanner 36mm 12 Point

• 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.

• 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.

• Metric sizes 9mm and smaller and sizes 36mm and larger do not have the 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.
