Here we have a pack of 12 black Countersunk Japanese Style Phillips Screws as used to secure tank badges on your bike.  

You need 4 per set of tank badges so have some spare. Buy as many packs as you need. They are M3.  In very rare cases M4 may have been used and if this turns out to be the case I can make a simple free of charge replacement.

Please use some copper slip grease (to ensure they do not seize up in the future. This is always a good idea).

Thanks for looking!
