Most relay racks / two post racks from US sources
(Hammond, Middle Atlantic, Chatsworth) which don't use
nuts seem to ship with 10-32 US threaded holes. All of
the cage nuts that mount in square holes seem to be M6
as they all come from China/Taiwan.
I am not sure the last time I saw something 12-24 threaded.
Then there are the weird 23" heavy gauge steel relay
racks used by some old telecom stuff that come untapped,
if you want to mount stuff in it you need to bring a tap
kit and power drill.

I think even here in the US, square holes and M6
cage nuts and screws are pretty much standard. At
least in data centers. Telco might still use 12-24.

I've seen lots of M6 in the stuff from China, and of
course 12-24 and 10-32 from US sources... But never M5.

Rack screw can be 10-32, 12-24, M5, M6. And
rack rail can be threaded, round hole, square
hole. Too many options.

I know on Cisco switches you could turn the ears
around and the holes would line up so you’d get
more switch in front of the rails.

That's a good idea.
If there are not holes, is there a small
screw type that is short and self-tapping?
Not sure the best way to mount the ears if
the holes for the ears don't exist on the
switch.

Add mounting ears farther back on the switch.

Subject: [AFMUG] Super long rack screw
This is really specific; don't ask why I
need it :)
But I need a standard rack threaded screw
that looks like a 6 to 7 inch long
motherboard standoff screw.
So it would stand a 1U switch forward from
the 19" rack about 6-7 inches.
I tried standard rack standoff modules, but
the space is too limiting.
