Product Description

Standard:F436M

Description:   

      F436M washers, also known as plain washers, are specified by the ASTM F436M standard. They are used in structural applications to provide a larger bearing surface and distribute the load when used with bolts or screws. The size range you mentioned, M12 to M100, refers to the metric diameter of the bolt or screw they are designed to work with.

      When specified with a "Black Oxide" finish, F436M washers have undergone a surface treatment process known as black oxide coating. Black oxide coating, also known as blackening, is a conversion coating that creates a thin layer of black oxide on the surface of the washer.

      The black oxide coating serves multiple purposes. First, it provides a degree of corrosion resistance, although its level of protection may not be as high as that of other coatings like hot-dip galvanizing or zinc plating. Second, the black oxide finish enhances the aesthetics of the washers, giving them a sleek black appearance. Lastly, the black oxide layer can improve the wear resistance and lubricity of the washers, facilitating smooth assembly and operation.

      F436M washers with a black oxide finish are commonly used in structural and industrial applications where both functionality and visual appeal are important. They find applications in construction, bridges, and other projects where high strength and reliability are required. However, it's essential to consider your specific application requirements, including environmental conditions and load requirements, to ensure that the black oxide finish meets your needs.

      Please note that while black oxide coating provides some corrosion resistance, it may not offer the same level of protection as other specialized coatings. If high levels of corrosion resistance are required, alternative coatings or finishes, such as hot-dip galvanizing or zinc plating, may be more suitable.
