Proto® Tether-Ready 9 Piece Black Chrome Non-Reversible Combination Ratcheting Wrench Set - Spline


Features and benefits

  • 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 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 help apply force over a large area helping to reduce risk of fastener rounding.
  • Spline design also helps prevent rounding of corners and other fastener 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.
  • Anti-Slip Design (ASD) open end.
  • Fractional spline wrenches can be used on fractional 4, 6, 12 point, spline and Torx® fasteners.
