SST wood connector bulldog® serrated on both sides hot-dip galvanized steel 50x17

In hot-dip galvanising, a zinc coating is applied to the component by immersing it in molten zinc and then spinning it off. DIN EN ISO 10684 restricts its application to steel fasteners with standard threads ranging from M8 to M64, as well as strength classes up to 10.9 for bolts and 12 for nuts. The average coating thickness for fasteners is 50 micrometres, which ensures corrosion protection for many years.
