SOLD NorCal - Early Dash Knob Set Screw (1 Viewer)

[Jimb074]

Vehicle Model

1. 40 Series

Missing one of the set screws for early style rotary dash knobs (head light/ wipers).

Edit - Spent some time at local hardware store yesterday, now believe the size to be M3 x 0.6 @ 12mm long. Of course they did not carry this exact size but was able to narrow down some of the questions. Surprisingly, found that a standard size 4-40 x 1/2" was a little loose but could be a last resort if I strike out here. Did also purchase an M3 x 0.5 thread in case I wanted to "force fit".

Can anybody help, either with cheap shipping or links to replacement options?
Thanks,
Jimmy

Still hoping that somebody out there has one of these unicorn horns in their parts yard or bin of misc. screws. Until then, I continue my search. Today I came across this thread from Krondor, also includes a link to some other detailed info. he discovered regarding JIS. Wanting to repost and/or include here to help the next one.

Early FJ40 light and wiper switch screw give away

If you ever lost one of the light or wiper switch screws, you probably found out that a standard modern M3 machine screw , course or fine, would not work as a replacement. So a few months ago, I did some research on the screw size for early wiper and light switches for FJ40s. It turns out that...

I may have one off my old light switch. I’ll go check and report back

Hi rd66toy, thank you for checking. Greatly appreciate your update.

Hi KT40, did check them. They did not have anything with correct thread pitch.
Thank you both.

I researched even more. Tough one to find.
My metric tap and die set actually has the tap and die. But when you search the internet, most everything is 0.050 pitch.

I found that interesting also, could find the tools to create but very little to go into it Did speak with Krondor regarding his link to shop in Australia. If no luck by next week, think I will be going that route.

Big shout out to Chase (red66toy) @ Cruiser Cult (Cruiser Cult Shop - https://cruiser-cult.myshopify.com/) for digging into his parts bin to find this screw. Many thanks, well received and GREATLY appreciated.

As an alternative to the original parts replacement, i did find this motorcycle carburetor shop on Ebay (KM Carburetor).

Pre 1967 JIS M3x6 M3x10 0.6mm Thread Pitch Screws - Made in JAPAN Ships from USA | eBay

These M3x6 and M3x10 screws follow the PRE 1967 JIS standard and have a 0.6mm pitch. M3 x 0.6mm Thread Pitch OLD JIS Pan Head Screws #2 Drive. NOT cheese grade knock off reproduction screws. Our screws are EXACTLY like what you would get from an OEM in the 1960's.

Fairly quick shipping and reasonable pricing (all things considered). Biggest thing was that the thread pitch was correct, it fit and would be functional. Slightly shorter than original and also a pan head style but with JIS head pattern. Was originally going to try and reshape the pan head to get it tapered for a better "seat" but was not needed.
