DIN6340 Washer/High Tensile Washer, M6-M30, Black Oxide

Standard:DIN6340
Description:

      DIN 6340 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 6340 standard, which specifies the dimensions and material requirements for these washers.

      The size range of DIN 6340 washers is typically specified in metric measurements, such as M6 to M30. This indicates that DIN 6340 washers can accommodate metric fasteners with diameters ranging from M6 to M30.

      Black oxide is a coating option available for DIN 6340 washers. Black oxide is a surface treatment process that involves forming a layer of black oxide on the surface of the washer, providing enhanced corrosion resistance. The black oxide coating also offers a measure of lubricity, reducing friction and torque during assembly.

      The benefits of choosing DIN 6340 washers with a black oxide coating include:

      1.Corrosion resistance: The black oxide coating acts as a barrier between the washer's surface and the surrounding environment, protecting it from rust and other forms of corrosion. This makes black oxide DIN 6340 washers suitable for applications exposed to moisture, humidity, or mild corrosive conditions.

      2.Enhanced aesthetics: The black oxide coating provides a sleek and uniform black finish to the washers, giving them an attractive appearance. This can be desirable for applications where aesthetics are important.

      3.Improved lubricity: The black oxide coating's inherent lubricity helps reduce friction during assembly, making it easier to tighten the fasteners and reducing the risk of galling or seizing.

      When selecting black oxide DIN 6340 washers, ensure that they meet the specific requirements of the DIN 6340 standard and any other relevant industry standards and specifications to ensure their quality and performance.

      It's important to note that while black oxide provides some corrosion resistance, it may not offer the same level of protection as other specialized coatings like hot-dip galvanization or zinc plating. Therefore, the suitability of black oxide DIN 6340 washers for a specific application should be evaluated based on the environmental conditions and the level of corrosion resistance required.
