Proto® JSCR08 Non-Reversible SAE Ratcheting Combination Wrench, 1/4 in Spline Wrench, 5 in OAL, 12 Points

• Black chrome finish is corrosion resistant and visually distinctive
• Non-reversing ratcheting wrenches can be flipped over to turn the fastener in the opposite direction
• Ratcheting spline box end is countersunk for easy application to the fastener
• Spline design also helps prevent rounding of corners and other fastener damage that could lead to foreign object damage (FOD)
• Spline design enables the wrench to contact conventional fasteners away from the corners, which help apply force over a large area helping to reduce risk of fastener rounding
• Spline design was created for use with specialty spline bolts which are used when weight and size of bolt heads must be minimized
• Anti-Slip design (ASD) open end
• Fractional spline wrenches can be used on fractional 4, 6, 12 point, spline and Torx fasteners
• Loads are kept off the corners of the fastener which helps prevent fastener rounding
• 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
• The high contact surface area which is away from fastener points enables turning of highly rounded 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
• Chrome-vanadium box ends and switch levers provide high strength and durability
