Odd Size Machine Screws
rdw777 Thu Mar 23, 2023 11:47 am
I picked up some 3-48’s today from our local hardware store (Higginbotham Bartlett) They were in a bin marked “gun screws”…. Thought they might work for prop screws if needed for my .020’s….. They are long and would need to be cut down, And a washer or spinner due to the Fillister head…..Look to be hardened….They had 5-40 and 2-56 as well and a lot of other odd sizes…So if you have a gun shop or random hardware store nearby they may just have that odd screw you’re looking for….

Robert, that's a good option. In this rural town about 8 years ago, I got on EBay a used but with good compression Enya .35-III TV. The seller put a photogenic nut, can't remember exact size may be a 1/4x20 or 5/16x18. The saving grace was I was the only bidder (wonder why 
), so got it for a song.
Visited the local Fastenal store. They had several bulk bags of 7x1.0 mm nuts (like 50 in each). He told me they had these for a very long time, slow mover, so he opened one and gave me 4 nuts for free.
Over time I have bought bulk hardware from them for the house and building my home rolled motorcycle trailer, that I couldn't find at the home improvement centers.
Other times, bought from sources recommended herein, bulk Allen cap head screws for engines.
I've found that the bolt cutters on my crimp tool are decent to trim 4-40, 6-32, 8-32, etc. screws. Smaller sizes, use cutting wheel and file end smooth & chamfer to easily thread.
Unfortunately we don't have gunsmith supplies here (that I know of) in this small town.

Yes GallopingGhostler,
If you do any work on the older Enya engines, all of them use the "old" JIS (Japanese Industry Standard) screws.
I have "four" different sources where I can get the JIS nuts, bolts, taps, and dies for the Enya engines.
Number "one" is Classic Fasteners which carry almost everything (nuts, bolts, taps, dies) for British cars, Japanese bikes
and other odd sized threads.
Next are, Fastener Express, McMaster-Carr, MSC Direct, New Star Fastenings, and Micro Fasteners.
One of them will have what I need?

Greatest blessing was when I was working in Okinawa in the mid 2000's, sosam117. The stores there had all the Japanese hardware I needed. Their 100 Yen stores (equivalent to our "Dollar" stores, but quality was much better) had small hardware packs in metric sizes, could find all my screws for my 1987 Suzuki LS650 motorcycle. Then in US, in some cases I substituted ANSI/SAE hardware when it was a nut with bolt situation, or sheet metal screw to hold plastic situation.
I was able to forage in my motorcycle junk hardware bin to find a prop nut for my Enya .19-VI TV auction buy. Used a small fender washer with hole reamed to proper size for prop washer, worked all and good.
Also done no-no's
in a few rare cases where with used engines (good experimental ground) retapped a hole in ANSI and ran a standard screw. But my standards are restoring usefulness versus maintaining historic quality.
