Standard:F436M
Description:
The F436M washer, also known as a metric structural steel washer, is a type of washer commonly used in structural applications that adhere to metric sizing standards. It is similar to the F436 washer but designed for metric fasteners.
The F436M washer is made from structural steel, providing high strength and durability for demanding applications where load-bearing capacity is critical.
F436M washers are available in various metric sizes, ranging from M12 to M100. The size is specified in millimeters and corresponds to the nominal diameter of the fastener it is designed to be used with.
In terms of surface finishes, F436M washers can be found in two main variants: plain and Dacromet.
1.Plain Finish: Plain finish washers have a basic, uncoated surface. They are typically used in applications where corrosion resistance is not a primary concern, such as in dry environments or when the fasteners are protected by other means (e.g., coatings, lubricants).
2.Dacromet Coating: Dacromet is a type of coating that provides excellent corrosion resistance to the washer. It is a thin, non-electrolytic coating that offers superior protection against rust and other forms of corrosion. Dacromet-coated washers are commonly used in applications where exposure to moisture, chemicals, or other corrosive elements is expected.
The choice between a plain finish and Dacromet coating depends on the specific requirements of your application, including the environmental conditions and the level of corrosion resistance needed.
