When selecting fasteners for connectors, match the base metal and corrosion resistance of the fasteners and connectors to maximize connection durability. Stainless steel connector screws should be used with stainless steel connectors. When galvanized and stainless steel parts are used together, galvanic corrosion can occur because the two metals (zinc and stainless steel) are electrochemically dissimilar. If the screw is galvanized and the connector is stainless steel, corrosion of the screw would begin with sacrifice of the zinc in the galvanized coating and then proceed with corrosion of the steel screw. Whether due to a galvanic or oxidative electrochemical process, corrosion can lead to the need for premature repair or failure of the connection.
