DIN6916 Washer/Hardened Steel Washer, M12-M36, Plain/Dacromet
Hardened Steel Washer Description:
The DIN 6916 Hardened Steel Washer is a type of flat washer designed to provide enhanced load distribution and protection for bolted connections, especially in high-stress applications.
In summary, the DIN 6916 Hardened Steel Washer is a critical component in applications requiring high strength, durability, and reliable performance.
· Heavy Machinery: Commonly used in construction and industrial machinery where high tensile strength is required.
· Structural Engineering: Suitable for use in structural applications, ensuring secure fastening of components.
· Automotive: Often found in automotive applications where durability and reliability are critical.
1.Plain Finish: The plain finish refers to an uncoated washer. It does not have any additional protective coating or treatment on its surface. Plain finish washers are typically used in applications where corrosion resistance is not a significant concern. They are suitable for indoor use or in environments where exposure to moisture or corrosive substances is minimal.
2.Dacromet Coating: Dacromet is a type of coating that provides excellent corrosion resistance. It is a thin, chromate-based coating that is applied to the surface of the washer. Dacromet-coated washers are highly resistant to rust and can withstand exposure to moisture, chemicals, and harsh environmental conditions. They are often used in outdoor applications, such as construction, marine, or automotive industries, where corrosion protection is crucial.
