  • Black chrome finish is corrosion resistant and visually distinctive
  • Anti-slip design (ASD) open end
  • 15 deg angled offset helps keep shank clear of obstructions
  • 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)
  • Box end is countersunk for easy application to the fastener
  • The high contact surface area which is away from fastener points enables turning of highly rounded fasteners
  • 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
  • Chrome-vanadium box ends and switch levers provide high strength and durability
