- 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
- 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 lever allows for easy changes in turning direction which helps improve speed
