- Spline design also helps prevent rounding of corners and other fastener damage that could lead to Foreign Object Damage (FOD)
- 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
- Chrome-vanadium box ends and switch levers provide high strength and durability.
- Box end is countersunk for easy application to the fastener.
- Metric Spline wrenches can be used on metric 4, 6, 12 point, spline and Torx fasteners
- The high contact surface area which is away from fastener points enables turning of highly rounded fasteners
