FOUND - Screws Needed For Starter Solenoid

Post by Seadog » Wed May 23, 2018 10:37 am

In resurrecting my starter solenoid, I managed to mangle one of the two rusty 4mm x 0.5 screws holding it together. I went to the hardware store to get replacements, but ISO 4mm seems to be a different thread pitch, which is 0.7. This is a bit of a mystery, since my JIS to ISO conversion chart tells me that the thread pitch for 4mm ISO and JIS are the same 0.7. I did a computer search and found another chart that claimed the JIS 4mm is 0.75 pitch. ????

Whatever the case, I need at least one replacement screw. Two would be better. If anyone has some in their hoard and is willing to share, I'd gladly pay for the screw(s) and postage.

I have some spare solenoids and will check what I have. Out visiting my friend today but will take a look tomorrow.

Thanks, G., but I found a couple of cap screws that did the trick. Now I can paint the top cap and set the switch aside until assembly time.

Great find. JIS cap screws. That's something special.
