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.

Love the black chrome but wish it was industrial finish. Teeth count is high so it works in small areas. I've applied about 35ft lbs of torque on it and it still works perfect. Love the low profile feature about these

I have been using the smaller sibling of this for years without a hitch. Needed the larger sizes for new job and I am just as happy with this one. Smooth ratcheting with medium-high tooth count. Would buy again.
