This is the Ultimate Racing clutch screw. Made of high quality steel and laser engraved. Designed with dual head, the inside is 3mm Allen and the outside is 5.5mm hex so you can use a nut driver/wrench. This gives you two easy ways to remove the clutch screw and a redundant option in case one of the two is damaged. The diameter is 10mm to completely cover the front clutch bearing.
