Bolts Buttonhead Chr Usa Sizes

14 products in Bolts Usa Sizes

Chrome buttonhead bolts in USA imperial threads from Gardner-Westcott and Colony. The smooth domed head suits builders who want a cleaner line on engine covers, derby covers, handlebar clamps, and visible brackets — less aggressive than a hex, less recessed than a flathead. Sizes from 1/4-20 through 5/16. Worth pairing across an entire engine side rather than mixing head styles on adjacent bolts.
