These screws are made with the old JIS spec threads for Japanese motorcycles and other equipment produced prior to 1967. As such, they do not have the dot indentation on the head that M3, M4, and M5 screws with the current ISO threads have.
KM Carburetor stocks more genuine JIS screws, nuts, washers and other hardware than anyone in North America (maybe even the world outside of Japan!) We carry all of the oddball fasteners to keep your Japanese motorcycle looking fresh including Japanese carburetor screws, engine case screws and old JIS thread pitch screws in a variety of finishes. We even have custom fasteners made for us by our manufacturing partners in Japan! All of our JIS hardware is Made in Japan so you know you're getting the real deal.
If you don't see it here, we can probably get it! Send us a message with your specifications and we will find it.
