I know it's an official size, but has anyone ever seen or used a #12 screw?

RE: #12 screws
I just checked our internal hole chart and even it jumps fom #10 to .25.
KENAT,
Have you reminded yourself of FAQ731-376: Eng-Tips.com Forum Policies recently, or taken a look at posting policies: http://eng-tips.com/market.cfm?

Fastenal has 'em in 18-8, but you never really know what you're getting with 18-8.
Just jumped out at me on this drawing that I'm looking at. I can't recall ever using a #12. Seems like most folks go for the ubiquitous 1/4-20.

Are you sure about racks? All the 19" racks I have seen use 10-32UNC or M6X1.
RE: #12 screws
We've got a #12-24 screw in one of our products. Our product is a bolt-on to existing equipment so we didn't have a choice in the matter.
If you think the #12-24 is weird, the same product uses a #18-18 screw. Try finding those on the shelf anywhere...

The 19" rack you are refering to are probably ETSI type(which uses M6) or WECO type or the cheapo economy versions (which use #10). Typical better quality EIA racks,unequal flange racks, seismic,etc.. (much more popular) all use #12-24. We get them from fastenal.. Ours are #12-24 x 1/2" ph pan hd type 23 zinc plated steel.

In the old-timey times there used to be a #14 machine screw as well, but I haven't seen one of those for a long time.

They wouldn't be referring to a M12, by any chance? As in 12mm... and the scale of the drawing is wrong...?
I once went to the hardware store for a 10-32 tap, came home with a 3/16"-32 tap. Didn't realize until I took it out of the package to use it. Measured... Yup 3/16". I kept it just as a reminder to read the label on things.

I have used #12 on tooling and other products, but not very common.
