Description:
The SAE washer, also known as a structural steel washer, is a type of washer commonly used in the United States. It conforms to the SAE (Society of Automotive Engineers) sizing system.
The SAE washer is made from structural steel, which is a type of steel specifically designed and manufactured for use in structural applications. It provides high strength and durability, making it suitable for demanding applications where load-bearing capacity is critical.
SAE washers are available in various sizes ranging from 1/4" to 3" in diameter. The size is specified in inches and refers to the nominal diameter of the fastener it is designed to be used with.
In terms of surface finishes, SAE 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.
