DIN6916 Washer/High Tensile Washer, M12-M36, Plain/Dacromet
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: plain and Dacromet.
Plain DIN 6916 washers do not have any surface coating or treatment. They are made from bare steel and provide basic protection against corrosion. Plain washers are typically used in applications where corrosion resistance is not a significant concern or where additional coating or protection measures will be applied.
Dacromet is a specialized coating option for DIN 6916 washers. It is a non-electrolytic, water-based coating that provides excellent corrosion resistance. Dacromet coatings are typically thin and uniform, offering a high level of protection against rust and other forms of corrosion. They are designed to withstand harsh environmental conditions, including exposure to moisture, salt spray, and chemicals. Dacromet coatings also provide good adhesion and are self-lubricating, reducing friction during assembly.
When selecting between plain and Dacromet 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, Dacromet-coated DIN 6916 washers would provide superior corrosion protection. For applications where corrosion resistance is not a significant concern or where additional protective measures will be applied, plain DIN 6916 washers may be suitable.
