Standard:SAE
Description:
The SAE washer, also known as a flat steel washer, is a widely used type of washer that conforms to the specifications outlined by the Society of Automotive Engineers (SAE). It is commonly employed in automotive and other mechanical applications to distribute the load of a threaded fastener, such as a bolt or a nut, and provide a smooth bearing surface.
Here are some details about the SAE washer:
Size range: The SAE washer is available in a range of sizes, typically specified in inches. The common size range for SAE washers is 1/4" to 3". This indicates that the washer is available in various diameters to accommodate different sizes of bolts or nuts.
Finish options: SAE washers are available in different finishes, including zinc plated and hot-dip galvanized (HDG).
1.Zinc plated: Zinc plating involves applying a protective coating of zinc to the washer's surface. This finish provides corrosion resistance, enhancing the washer's durability and preventing rust formation. Zinc plated SAE washers are commonly used in a variety of applications.
2.Hot-dip galvanized (HDG): HDG is a process in which the washer is immersed in a bath of molten zinc, resulting in a thicker and more durable zinc coating than standard zinc plating. HDG provides excellent corrosion protection, making it suitable for applications exposed to harsh environments or outdoor conditions.
Material: SAE washers are typically made of steel. The specific grade of steel used can vary, but it is often low or medium carbon steel.
Function: The primary function of the SAE washer is to distribute the load and provide a smooth bearing surface under the head of a bolt or the nut. It helps prevent damage to the mating surface, reduces the chance of loosening due to vibrations, and improves the overall stability and performance of the fastener connection.
