DIN 934 A2 stainless steel hex nuts with zinc coating are used in metric bolted joints where the risk of galling between stainless steel threaded components needs to be reduced. During tightening, stainless steel threads can be susceptible to galling, where the mating surfaces begin to adhere and can eventually cause the threaded joint to seize. The zinc coating provides a separating surface between the stainless steel threads, helping to reduce friction and the risk of galling during assembly. The range includes DIN 934 A2 ZN hex nuts with standard metric threads for industrial and engineering applications.
