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.
F436M washers are available with two common coating options: zinc plated and hot-dip galvanized (HDG).
Zinc plated F436M washers have a thin layer of zinc electroplated onto the surface. The zinc coating provides a sacrificial layer that helps protect the washer from corrosion. Zinc plating offers moderate corrosion resistance and is commonly used in indoor or low-corrosion environments.
HDG F436M washers undergo a hot-dip galvanizing process, where they are immersed in a bath of molten zinc. This forms a thicker and more durable zinc coating compared to zinc plating. HDG provides enhanced corrosion resistance and is suitable for outdoor, high-moisture, or corrosive environments.
When selecting between zinc plated and HDG F436M washers, consider the specific environmental conditions in which they will be used. If the application involves exposure to moisture, humidity, or corrosive substances, HDG F436M washers would provide better corrosion protection. For indoor or low-corrosion environments, zinc plated F436M washers may be sufficient.
