A fellow called the other day needing some 5/16-32 extra fine thread screws for an old shotgun. "Extra fine" is the term this fellow used, I'm not sure if this is correct. Our local sources did not have this screw. Brownell's also does not have it. Does anyone know of a good source for odd machine screws. Thanks. Greer

Did you try the local machine shop? They are very helpful usually. If not the various machinist supply houses carry nearly any standard thread ever used.. Some combinations were never standardized. These one would have to make for themselves..

You would probably have to make up from a lathe turned blank and use a die available from a supply house. McMaster Carr carries such a die for about $36.00 Their web address is mcmaster.com. A screw of this thread pitch will be very difficult to locate. Especially if you need an odd head shape.

Thanks for the replies. I did check the local industrial supply shops with no luck. I found some companies on the web that might can help the fellow. Aaron's Machine screw's @ 1-877-838-3575, and Bolt Depot @ 1-866-337-9888. They at least may know where to send him. Thanks again. D.Greer

Doug, It probably would cost less just to get someone with a lathe to turn a screw. If you buy a special die, you still have to have someone make the screw and thread it. the thread can be easily turned on a lathe. I usually take a screw and thread it then modify the head to match what is needed ........ fwiw don
