Proto J8182-T500 Box Wrench Ring Spanner 5/8 x 11/16 inch 12 Point Polished

• Full polish wrenches meet and exceed stringent aerospace specification AS4984A which requires tools to have a thicker nickel-chrome coating for greater corrosion-resistance..

• 12 point box end allows for fine indexing, helping to improve speed and access. Fits 4, 6 and 12 point fasteners.

• 60° deep offset helps improve access to deeply recessed fasteners.

• Offset handle helps keep knuckles clear of obstruction to help save time.

• 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.

• Proto Tools have been manufactured in the USA for over 110 years, made to standards suitable for stringent aerospace requirements and heavy mining applications.
