One of mine is missing. I notice the thread is 40tpi, but what size is it? Of course, this part is missing from the appendix for fasteners in the catalog.
I presume that this is a BS BA screw?

Thanks,
Probably easier to just buy a new plate, complete with screws.

Tempted to just tap the hole to 8/32 and be done with it.
