Bonding screw threads at panel stripped

[Fred B]

I usually just pick up scrap 12gauge off the floor and ask one of the hvac guys for a sheet metal screw.

Has worked fine for many 1200amp services

Have never had a breaker trip since doing this.

Jk

I hope that was tongue in cheek response. But under those conditions not likely to have it trip a breaker, a large fault would make that #12 a fuse link and probably blow out before the higher 1200A would, or may simply act as if there is no ground and behave as an ungrounded system until you have 2 faults of that 1200A 3ph.
