Proto Combination Wrench, Reversible, Measurement System: Imperial, Ratcheting/Spline Wrench, 5/16 in Wrench Opening, 12 Points, 72 Geared Teeth, 5-1/2 in Overall Length, 15 deg Offset, 11/16 in Open End Width, 1/8 in Open End Thickness, 21/32 in Box End Width, 1/8 in Box End Thickness, ASME Specified Specifications Met, Chrome Vanadium Steel, Polished Chrome/Black

ITEM FEATURES:

• Fractional spline wrenches can be used on fractional 4, 6, 12 point, spline and Torx fasteners
• The chrome vanadium switch lever allows for easy changes in turning direction which helps improve speed
• 15 deg angled offset box end helps keep shank clear of obstructions
• Anti-slip design (ASD) open end
• Black chrome finish is corrosion-resistant and visually distinctive
• Box end is countersunk for easy application to the fastener
• Spline design enables the wrench to contact conventional fasteners away from the corners, which applies force over a larger area, reducing risk of fastener scoring and helps prevent rounding of the corners and other fasteners damage that could lead to foreign object damage (FOD)
• The high contact surface area which is away from fastener points enables turning of highly rounded fasteners
• Chrome vanadium box ends and switch levers provide high strength and durability
• Feature a spline ratcheting end to turn multiple fasteners while helping increase the force applied to the fastener
• Spline tools engage the flats of conventional nut fasteners to move the loads away from the corner of the fastener and transfer them over a broader surface area
• Helps increase the force that can be applied to a fastener
• Helps reduce damage to fasteners, easy to access restricted spaces compared to a socket
