Gardner-Westcott engine hardware addresses the fastener requirements of Harley-Davidson engine work with almost 50 years of accumulated knowledge about what each application actually needs. Where most fastener suppliers offer standard-grade hardware and leave the fitment research to the buyer, Gardner-Westcott has catalogued the specific thread pitch, diameter, length, and grade requirements for every Harley-Davidson engine application — engine mounting bolts, cam cover fasteners, rocker box hardware, and primary side cover screws — across the full generation range from Shovelhead through Evolution, Twin Cam, and Milwaukee-Eight. Their available finishes reflect the range of build intentions: chrome-plated hardware for show builds, cadmium for period-correct restoration of pre-Evolution machines, stainless for longevity, and standard zinc for functional rebuilds where budget matters. The precision specifications eliminate the guesswork that leads to stripped threads and cross-referenced returns. For a Panhead restoration demanding the correct thread standard or a Twin Cam engine rebuild where cam cover hardware needs to match, Gardner-Westcott has the specific part identified. Iron City Motorcycles, an authorised Harley-Davidson dealer in Leeds, stocks Gardner-Westcott engine hardware for UK builders and restorers who won't accept a fastener approximation.
