We try to provide the full range of JIS screws found on Japanese bikes, from M3 to M8. Full thread or 50mm thread for longer screws. Four common steel treatments and stainless are proposed. Please read our explanation of plating if you are not sure which one you need. These are JIS (Japan Industrial Specification) like on the original bikes, you should have JIS screwdrivers in your toolbox or check the tool page.
About the dot: there is a common understanding that JIS screws have a dot on the head for identification. This is true for smaller sizes but on M6 I have never seen this dot!
In case you need a size or a material and treatment not proposed, please ask by mail we have access to many others not stocked here.
