Good morning.
I am reviewing the suitability of serrated head screws in grounding and
bonding applications. I am aware that these screws are good at resisting
vibration, but I've not seen them used for grounding and bonding purposes.
I question this application since, while the serrations
Hi Peter:

suitable for a PE circuit connection.
The biggest problem is whether a certification house will accept the
construction. Be prepared (plan B) to replace the screw with a conventional

listed metal junction boxes and lighting fixtures etc. for building wiring
(US). Some of them are serrated. They would be used with solid copper or ring
terminals.

current, these little points will melt and/or vaporize. The military prefers a
strap which terminates in a flat ring-lug, with the lug
