Colony Nuts Metric

27 products — part of all Nuts Metric

Colony metric nuts cover the modern Harley-Davidson fastener requirement for any model that uses metric hardware — increasingly common across current Touring, Softail and Street lineups alongside traditional USA-thread specifications. Colony produce their metric fasteners with the same attention to dimensional accuracy and finish quality that made them the benchmark for USA-thread reproduction hardware, meaning their metric range is equally at home on a factory restoration or a custom build using metric aftermarket components. Correct nut sizing and thread pitch is critical on Harley-Davidson — wrong-spec hardware either strips thread or leaves fasteners dangerously under-torqued. Colony offer a broad selection of styles, finishes and thread sizes to cover both standard hardware replacement and show-quality chrome upgrades. Iron City Motorcycles, Leeds' authorised Harley-Davidson dealer, carries Colony metric fasteners as part of a complete fastener inventory. Whether you are reassembling an engine or installing accessories, quality nuts make the difference. Browse the full Colony Nuts Metric range below.
