Electro zinc galvanising (zinc plated) and hot dipped galvanising (HDG) are surface coatings that are safely applied to fasteners grade 4.8 and grade 8.8. Electro zinc plating provides an aesthetically appealing bright silver finish and is more suitable for interior use. HDG (hot dip galvanised) is recommended for use in exterior applications where corrosion is a factor to be considered. Due to the risk of hydrogen embrittlement, it is not recommended to zinc plate or HDG high strength fasteners grade 10.9 or higher.
