Nuts Flexlock Chrome Usa Sizes

4 products in Nuts Usa Sizes

Chrome flexlock nuts in USA thread sizes — a deformed thread or nylon insert holds them against vibration, which is a real issue on any V-twin and especially on rigid-frame builds. Supplied by Colony, Gardner-Westcott, and a handful of MCS-sourced sizes. Often the sensible call where a plain hex would walk loose, without needing threadlocker. Covers 1941–2002 Big Twin / XL through to 2010–2026 Softail, Dyna, and Touring.
