Sheetmetal screw for grounding #14

[Jim W in Tampa]

Sections 250.8 (1)(3)(7)(8) all have the word listed. I would think that any method used would have to be listed or identified for use. IMHO, just because the NEC drops a specific language doesn't mean you are free to use the mounting screw inside a 4" square box to secure the ground wire.

I know that wasn't what the OP originally asked but as long as we're discussing the possibility of using a sheet metal screw the conversation could go from using a separate sheet metal screw to using any available sheet metal screw. IMHO, it's not identified for the specific use.

So if i use a nut and bolt are you suggesting they must be listed ?
