B=black, C=cadmium plated, N=nickle plated.

1/8" N
5/32" B
3/16" both C and N
7/32" B
1/4" both C and N
9/32" B
7/16" N
15/32" B
17/32" B

There are others 2-56, 4-40, and several others, but the above are all the 3-48 sizes used in 
the SCR-274N.

I wish we could find a similar list for the ARA (probably the same as for the '274N) and for the 
AN/ARC-5 (possibly simplified or reduced numbers).

I also talked with our local Fastenal outlet. Getting 3-48s is not trivial now. I am going down to 
talk with them this morning sometime.

I bought a couple of hundred of at least two sizes of 3-48 several years ago, but all in 
stainless steel as, at the time, those were far less expensive than brass.

More later.
