The military doesn’t like that method. I think the primary reason is that the
serrations form small point-contact connections, and, under heavy fault
current, these little points will melt and/or vaporize. The military prefers a
strap which terminates in a flat ring-lug, with the lug
I just checked my collection of extra green bonding screws that come with the
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.

Hi Peter:
If the serrated head screw is suitable for a mains circuit connection, it is
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
screw and lockwasher.

loosening of the screw, they do not bite into the metal beneath the

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.
