Hot Dip Galvanized Hex Head Bolts with Plain Washers, Spring Washers and Hex Nut Used for Photovoltaic, Wind, Electricity
Hot-dip galvanizing is to apply a zinc layer on the screw at high temperature, so that a relatively thick protective layer can be formed, which has a better anti-corrosion effect.
American Standard has conducted a large number of tests on various screws and nuts. The galvanizing thickness of medium-sized bolts (M6~M10) is about 5~8 microns. The performance level of hot-dip galvanized ordinary nuts is 4.8-10.9, the specifications are M12-M48, and the coating thickness must be ≥54 microns. This thickness standard has strict requirements!
In general, hot-dip galvanized screws perform better in corrosion resistance. If you need screws that are used in harsh environments for a long time, hot-dip galvanizing is a good choice.
