Hey there everyone,

Got some question on earthing standard. Is IEC Standard ever stated type of material for bolt/screw that shall be clamp with earthing wire?

Right now I'm going to use a Zinc Coated screw for earthing bond instead of brass or stainless steel, but all known that zinc coated easy to rust under humid condition. If the zinc coated screw start to rust, will it spread through other contact surface?

Please advise.
