Standard:DIN6916
Description:
The DIN 6916 washer, also known as a structural steel washer, is a type of washer that conforms to the DIN 6916 standard. These washers are commonly used in construction, engineering, and industrial applications where high load-bearing capacity and durability are required.
The M12-M36 size range indicates that these washers are suitable for use with bolts or threaded fasteners ranging from M12 to M36 in diameter.
When it comes to surface finishes, DIN 6916 washers can be available with two common options: zinc plating and hot-dip galvanizing (HDG).
Zinc plating involves applying a protective layer of zinc to the surface of the washer. This coating provides corrosion resistance, helping to prevent rust and extending the lifespan of the washer. Zinc-plated DIN 6916 washers are suitable for applications where moderate corrosion resistance is required.
Hot-dip galvanizing (HDG) is a process in which the washer is dipped into a bath of molten zinc, resulting in a thicker layer of zinc coating compared to zinc plating. HDG provides enhanced corrosion protection, making it suitable for applications where the washer will be exposed to harsh environments or corrosive substances.
The choice between zinc plating and HDG depends on the specific requirements of the application, including the level of corrosion resistance needed and the environmental conditions the washer will be exposed to. Both options offer improved corrosion resistance compared to plain steel washers, providing greater durability and longevity.
