SAE Flat Steel Washer 1/4" - 3", Zinc Plated/HDG For Construction
Flat Steel Washer Description:
SAE flat washers are flat circular washers that conform to the standards set by the Society of Automotive Engineers (SAE). These washers are used in a wide range of automotive, industrial, and mechanical applications where a flat bearing surface is required to distribute loads and prevent damage to the material being fastened.
SAE flat washers are typically made from steel, which provides strength and durability necessary for various applications. The steel used can be plain carbon steel or alloy steel depending on the specific requirements of the application.

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.
