6 products in Nuts Usa Sizes
Stainless acorn nuts in USA thread sizes — resist rust and road-salt pitting far better than plated chrome, which matters if you ride British winters or live near the coast. Supplied primarily by Colony and Gardner-Westcott, with MCS filling specific sizes. Common fitments include 1941–2002 Big Twin / XL, 1984–2025 exhaust-to-head bolts, and 2010–2026 Softail, Dyna, and Touring axle nuts.
