Product Info


  • 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
