Proto JSBV3236 1 X 1-1/8 Reverse Spline Box Wrench
Proto JSBV3236 Features
- 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
