Standard:F436M
Description:
The F436M washer, also known as a metric structural steel washer, is a hardened steel washer commonly used in structural applications that adhere to metric sizing standards. It is designed to meet the requirements of ASTM F436M, which is a standard specification for hardened steel washers for metric structural steel bolts.
The F436M washer is available in a range of metric sizes, typically ranging from M12 to M100. The size is specified in millimeters and corresponds to the nominal diameter of the metric fastener it is designed to be used with.
In terms of surface finishes, F436M washers are commonly available with two main options: zinc plated and HDG (Hot-Dip Galvanized).
1.Zinc Plated: Zinc plating involves applying a thin layer of zinc coating to the surface of the washer. This provides moderate corrosion resistance and helps protect the washer from rust and other forms of corrosion. Zinc-plated F436M washers are often used in applications where the washer is not exposed to harsh environments or where additional corrosion protection measures are applied.
2.HDG (Hot-Dip Galvanized): HDG involves immersing the washer in a bath of molten zinc, forming a thick, protective coating on the surface. HDG provides excellent corrosion resistance, making it suitable for applications where the washer will be exposed to harsh or corrosive environments. HDG F436M washers are commonly used in outdoor applications, such as construction, infrastructure, and marine projects.
The choice between zinc plated and HDG depends on the specific requirements of your application, including the environmental conditions and the level of corrosion resistance needed.
