Standard:DIN6916
Description:
DIN 6916 washers, also known as chamfered washers, are specified by the German standard DIN 6916. These washers are designed for use with high-strength structural bolts and are commonly used in construction and engineering applications. The size range you mentioned, M12 to M36, refers to the metric thread size of the bolts they are designed to work with.
When specified with a "Hot Dip Galvanized" (HDG) finish, DIN 6916 washers have undergone a process called hot-dip galvanizing. Hot-dip galvanizing is a method of coating steel with a layer of zinc to provide corrosion protection. The washers are immersed in a bath of molten zinc, allowing the zinc to bond with the surface of the washers, forming a thick and durable coating.
HDG-coated DIN 6916 washers offer excellent corrosion resistance, making them suitable for outdoor or highly corrosive environments. The thick layer of zinc acts as a barrier, protecting the washers from rust and corrosion. Hot-dip galvanizing provides a long-lasting and robust finish, making it a popular choice for applications where corrosion resistance is critical, such as in construction, infrastructure, and marine projects.
When selecting DIN 6916 washers with an HDG finish, it's important to ensure that they comply with the required specifications and standards for your application. Consult the relevant industry standards, such as ISO, EN, or national standards, to determine the specific requirements for the washers you need.
