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.
