WR BOX REV SPL 1 X 1-1/8

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.
