Product Info


  • 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
  • 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
  • Ratcheting wrenches feature a spline ratcheting end to turn multiple fasteners while helping increase the force applied to the fastener
