Our electroplated zinc coatings are designed to give sacrificial protection to the fasteners in an electrogalvanic corrosion scenario as well as resistance to corrosion (tested to BS EN ISO 9227: 2012). In addition to pure zinc coatings, we use specialist coatings such as zinc with yellow di-chromate passivation to give additional resistance to corrosion and chemical attack. Stainless Steel Evolution Fasteners use 300 series austenitic stainless steels in our fasteners where the ultimate in corrosion resistance is demanded by the application. These screws are constructed from SAE 304 (Euro Class A2) stainless steel and and SAE 316 (Euro Class A4). TESTING Evolution Fasteners test all of our screws and coatings to the highest possible standards in our own in-house testing laboratory. Our primary method is through Neutral Salt Spray Testing to BS EN ISO 9227: 2012 but we also subject our coatings to testing in acid, alkalis, solvents and organics to ensure that the coatings we supply are of premium quality.
