What Is a USS Flat Washer?
A USS flat washer is a type of flat washer adhering to the United States Standard (USS).
Primarily employed alongside bolts or nuts, these washers serve to distribute loads and safeguard surfaces. By increasing the contact area and reducing the load per unit area, they enhance friction, thereby preventing the loosening of bolts or nuts.
USS flat washers find widespread use in construction, machinery manufacturing, automotive assembly, household appliances, and various DIY projects. Comprising elements such as outer diameter, inner diameter, thickness, and material composition, they are valued for their robustness, heat and corrosion resistance, versatility, and cost-effectiveness. Users must ensure the selection of the appropriate type, size, material, and surface treatment when employing USS flat washers.
