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 the Japanese used a different screw pitch for some pre 1967 screws and bolts.

Early JIS screw size differences


Instead of a M3x.5 or M3x.35 they used a M3x.06.
It took a fair amount of research to even find a replacement M3x.06 screw let alone a company that still made and sold them.
At last, the research paid off. I found a company through our friends down under called classic fasteners.

Unfortunately they are not an exact match. The screws are pan head instead of the original flat head machine screw. For a detailed restoration, they may not work for you, but for the majority of people, no one will look that closely at the screw holding your vintage knob in place. Instead they will marvel at the knob itself.

Anyway, the shipping and handling from Australia is pretty killer for a .50 cent screw. So I bought a few extras. They have been sitting on my shelf for a while collecting dust. If anyone needs an extra 1 or 2 for their restoration, I would be happy to stick them in an envelope and send them your way. If you are planning on reselling the switch once complete, I ask that you purchase your own from the link provided:
