Microair Transponder brass screws?

Anybody know a source for metric brass screws for the Microair
transponder? The ones that came with it are steel and I need to cut
down on magnetic interference. I think they are 12mm x 4mm dia x 0.8mm
pitch.

I could be wrong, but that seems like splitting hairs. Isn't there some
much more significant items that could be worked on to meet you goals, than
1/2" long screws?

How much difference could that make, compared to the other steel or
electromagnetic influences within the radio?

are they stainless steel?
austenitic stainless is non magnetic.

yes, but most fasteners are cold worked 301, and seem to be quite
ferromagnetic.

That said, heat them up pretty hot (well into the red region) and
water quench them; dead soft, and non-magnetic.

I did a REALLY MEAN thing to my son's science class 15 or 20 years ago
.... took about 4 inches of 301 rolled flat strip (about 45C
Rockwell) and heated one end with a torch, water quenched it.
Polished it all up, sent it and a magnet to school. One end stuck
QUITE well, one not at all ... told them if any student of teacher
could explain why, they could have some reward ... don't remember what
I offered. No one had any idea.
