DIN6916 Washer/High Tensile Washer, M12-M36, Zinc plated/HDG
Standard:DIN6916
Description:
DIN 6916 washers, also known as high tensile washers or structural washers, are commonly used in applications that require high strength and load-bearing capabilities. These washers conform to the DIN 6916 standard, which specifies the dimensions and material requirements for these washers.
The size range of DIN 6916 washers is typically specified in metric measurements, such as M12 to M36. This indicates that DIN 6916 washers can accommodate metric fasteners with diameters ranging from M12 to M36.
DIN 6916 washers are available with two common coating options: zinc plated and hot-dip galvanized (HDG).
Zinc plated DIN 6916 washers have a thin layer of zinc electroplated onto the surface. The zinc coating provides a sacrificial layer that helps protect the washer from corrosion. Zinc plating offers moderate corrosion resistance and is commonly used in indoor or low-corrosion environments.
HDG (hot-dip galvanized) DIN 6916 washers undergo a hot-dip galvanizing process, where they are immersed in a bath of molten zinc. This forms a thicker and more durable zinc coating compared to zinc plating. HDG provides enhanced corrosion resistance and is suitable for outdoor, high-moisture, or corrosive environments.
When selecting between zinc plated and HDG DIN 6916 washers, consider the specific environmental conditions in which they will be used. If the application involves exposure to moisture, humidity, or corrosive substances, HDG DIN 6916 washers would provide better corrosion protection. For indoor or low-corrosion environments, zinc plated DIN 6916 washers may be sufficient.
