- Black chrome finish is corrosion resistant and visually distinctive
- 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 fractional spline wrenches can be used on fractional 4, 6, 12-point and spline fasteners
- The high contact surface area which is away from fastener points enables turning of highly rounded fasteners
- The chrome-vanadium switch levers allows for easy changes in turning direction which helps improve speed
- Chrome-vanadium box ends and switch levers provide high strength and durability
