Stanley Proto JSBV1214 Double Box Racheting Spline Wrench 3/8 X 7/16

Product Description PROTO JSBV1214 Black Chrome Reversible Ratchet Wrench 3/8" x 7/16" - Spline From the Manufacturer Proto Spline Tools are designed to service high tensile strength fasteners used widely on military and commercial aircraft and in heavy machinery applications where vibration is prevalent. They are also used in automotive and industrial areas where high performance torque needs to be achieved. The Spline profile allows a higher torque to be applied before rounding of the fastener corners occurs. The applied loads are moved away from the fastener corners which allow the spline wrench to turn fasteners that are already worn or rounded.

• Spline fasteners help tighten high strength bolts which are used in high torque load applications.
• Spline helps reduce foreign object debris (FOD) by having a precise fit between the fastening tool and its fastener.
• Black chrome finish is corrosion resistant and visually distinctive.
• Ratcheting spline box end is countersunk for easy application to the fastener.
• The fractional spline wrenches can be used on fractional 4, 6, 12 point and spline fasteners., Imported
