Boy you guy sure get testy when someone challenges you. Wish I had not brought it up. After seeing the comments and the counter comments I have concluded that if you are using NM cable and it contains a gouunding conductor ir can be bonded to the box by a screw of any discription and if it is a a ground screw that purchased at the supply house it probably will be green. Nothing in the code book requires it to be listed. So we are talking about a judgment call as to whether it is effectively bonded. So now let's talk about the fact that there are no requirements for anything to be UL listed. Or, lets talk about whether the jumper to the box for our NM cable installation is a bonding conductor or a grounding conductor. By the way, I miss spoke the situation, the screw is a 10/32 not an 8/32
