WR BOX REV SPL 5/8 X 11/16

Features: Black chrome finish is corrosion resistant and visually distinctive | Ratcheting spline box end is countersunk for easy application to the fastener | 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 | Spline design was created for use with specialty spline bolts which are used when weight and size of bolt heads must be minimized | 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
