I'd like to get a hold of one 4-48 screw to test to see if it
fits into the business (test contact) end of a Federal test
indicator I have. If it fits I will need one or 2 screws at
least 1/2" long, any head or no head, but just to test any 4-48
thread should do. Tough to measure just what it is, but it's not
4-40 or any M3 I tried. Any help appreciated

Standard indicator points are 4-48 thread, check the catalogs. 48 tpi
is a little fine for it, but I've used a sliver of fine-grained wood
in the past to check internal thread pitch. Whittle it down, screw it
into the hole, back it out and check the pitch with a thread pitch
gauge.


I tried that at first, but as you say 4-48 was too fine to get a good reading
