ZINC/HDG Hard Steel Washers M12-M36 DIN6916 For Construction
Standard:DIN6916
Description:
The choice between the plain finish and Dacromet coating depends on the specific requirements of your application. If you anticipate exposure to moisture, chemicals, or corrosive substances, Dacromet-coated washers would be recommended. However, if corrosion resistance is not a major concern, plain finish washers can be suitable.
It's important to note that regardless of the finish, DIN 6916 washers in the M12 to M36 size range are made from hardened steel and provide high-strength and load-bearing capabilities. The washers' primary function is to distribute the load and ensure even pressure distribution when securing bolts or nuts in structural or heavy-duty applications.
· Load Distribution: Effectively spreads the load of a bolt or screw, minimizing the risk of surface damage to the material being fastened.
· Increased Durability: The hardened steel construction provides resistance to wear, making these washers ideal for long-term use in demanding environments.
· Corrosion Resistance: Many hardened steel washers are treated or coated to prevent rust and corrosion, enhancing their lifespan in various conditions.
