Anti-Slip Design (ASD) open end
Black chrome finish is corrosion resistant and visually distinctive
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
Spline design enables the wrench to contact conventional fasteners away from the corners, which applies force over a larger area, reducing risk of fastener scoring and helps prevent rounding of the corners and other fasteners damage that could lead to Fore
Spline design was created for use with specialty spline bolts which are used when weight and size of bolt heads must be minimized
The high contact surface area which is away from fastener points enables turning of highly rounded fasteners
