Standard:F436M
Description:
F436M 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 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 F436M washers is typically specified in metric measurements, such as M12 to M100. This indicates that F436M washers can accommodate metric fasteners with diameters ranging from M12 to M100.
Black oxide is a coating option available for F436M 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 F436M 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 F436M 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.
When selecting black oxide F436M washers, ensure that they meet 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 F436M washers for a specific application should be evaluated based on the environmental conditions and the level of corrosion resistance required.
