Galvanised bolts have superior corrosion resistance to zinc plated for long life in external applications. The bolts are dipped in molten zinc and spun to remove the excess leaving a minimum 40 mu layer of zinc. Hot Dip Galvanised nuts have oversized threads to accomodate the zinc layer on the bolt threads.
