Abstract
An improved grounding stud/nut sub-assembly for use in automobiles and the like is provided wherein the nut has a thickened washer portion to facilitate assembly of the nut and washer together onto an automotive substrate. The nut also has a swagged, flattened or distorted thread to make it a prevailing torque nut to hold the final assembly securely in place, as well as to strip paint from the threads of the stud in an interim step during the assembly. The stud also has a washer portion to achieve an appropriate stand off of the ground wire from the substrate and to protect the weld gun collet from the heat of the welding.
