121 products in Bolts Metric Sizes

Chrome allen bolts in metric threads from Gardner-Westcott, Colony, and Harley-Davidson genuine. Modern Twin Cam and Milwaukee-Eight bikes mix metric and imperial hardware — these cover the metric side, mainly engine cases, primary covers, and accessory mounts. Standard M6, M8, M10 in OE-matched lengths. If you're swapping a single bolt, check the head and thread on the original first; Harley alternates between styles even on adjacent fasteners.
