Greetings NEC Friends,
Is a 10-32 grounding screw installed in a metal box required to be green?

Answer:
Hi Adam,
Thanks for the question. This gets sent in a lot. There is no requirement in the NEC that a 10-32 screw used for connection of grounding or bonding conductors be green. Manufacturers sometimes use the color green when producing grounding and bonding means and equipment that could be installed for the connection of grounding or bonding conductors within metal boxes.
