Radius Rod Jam Nut Aluminum Wrench for Sprint Cars & Midgets.

The perfect wrench for the 5/8" (3/4" hex) aluminum jam nuts found on midgets and sprint cars.

These specially made aluminum wrenches grab 4 of the 6 sides of your jam nuts to reduce rounding off, unlike a standard 3/4" wrench. 

Hole is .57" so wrench can be conveniently stored on any shock or radius rod rack utilizing a 1/2" pin.
