Product Description

Standard:F436

Description:

      F436 washers, also known as high tensile washers, are widely used in applications that require high strength and load-bearing capabilities. These washers are designed to distribute the load of the fastener over a larger area, providing increased stability and reducing the risk of damage to the fastened materials.

      The size range of F436 washers is 1/4" to 4", meaning they can accommodate fasteners with diameters ranging from 1/4 inch to 4 inches. This versatility makes them suitable for various construction and structural projects.

      Black oxide is a coating option available for F436 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 F436 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 F436 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, such as architectural or decorative projects.

      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.

      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 Dacromet. Therefore, the suitability of black oxide F436 washers for a specific application should be evaluated based on the environmental conditions and the level of corrosion resistance required.
