3685 Brake Rotor Screws & Nuts for 1973-1986 FX

This Colony hardware kit is specifically designed for mounting brake rotors on 1973–1986 FX models, including the FXB Sturgis, FXWG Wide Glide, and FXEF Fat Bob. These screws are intended for 5-hole discs and work perfectly with both wire and cast wheels. Replacing rotor hardware is a critical safety step whenever you swap out discs, as old bolts can stretch or become brittle over time. This kit replaces OEM 3685 and provides the secure, high-strength fastening required for reliable braking performance. It is a straightforward, professional-grade solution for anyone restoring or maintaining the braking system on a classic FX-series shovelhead or early Evo.
