Spline Non-Reversing Combination Wrenches, 9/16 in Opening, 7 1/2 in

Description

• Fractional spline wrenches can be used on fractional 4, 6, 12 point, spline and Torx® fasteners
• 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 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 Foreign Object Damage (FOD)
• The high contact surface area which is away from fastener points enables turning of highly rounded fasteners
