Product Description

Standard:DIN9021

Description:

      DIN 9021 washers, also known as plain washers or flat washers, are specified by the German standard DIN 9021. These washers have a flat circular shape with a central hole and are used to distribute the load of a fastener, such as a bolt or screw, over a larger surface area. They help prevent damage to the surface being fastened and improve the stability and load-bearing capacity of the connection.

      When specified with a "Hot Dip Galvanized" (HDG) finish, DIN 9021 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 9021 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.

      The specified size range, M6 to M30, refers to the metric thread size of the bolts or screws that the washers are designed to work with.

      When selecting DIN 9021 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.
