• Features

• Metric spline wrenches can be used on metric 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 was created for use with specialty spline bolts which are used when weight and size of bolt heads must be minimized
• 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
