Standard:SAE
Description:
SAE washers, also known as high tensile washers, are types of flat washers that comply with the Society of Automotive Engineers (SAE) standards. These washers are commonly used in automotive and mechanical applications to provide a smooth bearing surface and distribute the load of a threaded fastener, such as a bolt or a nut.
The term "high tensile washer" refers to the washer's ability to withstand high tensile forces or loads. These washers are designed to be used with high-strength bolts or studs, which are typically made from alloy or carbon steel and have high tensile strength.
The size of the SAE washers is specified by the nominal diameter of the bolt they are intended to be used with. In your case, the size range you mentioned is 1/4" to 3". This means that the washers can be used with bolts or studs that have a diameter within this range.
The "black oxide" coating on these washers refers to a surface treatment that provides corrosion resistance and a dark appearance. Black oxide coatings are commonly used in fasteners and other metal components to protect them from rust and enhance their aesthetic appeal.
In summary, SAE washers or high tensile washers are flat washers that comply with SAE standards and are designed to be used with high-strength bolts or studs. The 1/4" to 3" size range indicates the compatible bolt diameters, and the black oxide coating provides corrosion resistance and a dark finish.
