Am looking for masking caps with a "washer" feature to not only mask the stud threads but also an area around the stud for grounding purposes. Have looked at 3 manufacturers of plugs and caps and have not had any luck in finding an off-the-shelf item. Stud is 1/4-20 x 3/4 long and need about a 1/2" diameter paint-free area around stud. In the past have used a metal washer and regular cap to get the proper masking but would be nice to have a rubber cap do it all.
