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: zinc plated and HDG (Hot-Dip Galvanized).
1.Zinc Plated: Zinc plating is a common surface finish for washers. It involves applying a thin layer of zinc coating to the surface of the washer. Zinc plating provides moderate corrosion resistance and can help protect the washer from rust and other forms of corrosion. It is 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 is a more robust and durable surface finish for washers. It involves immersing the washer in a bath of molten zinc, which forms 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. It is 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.
