Proto JSBV2428 3/4 X 7/8 Reverse Spline Box Wrench

Product Description

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.
