Features and Benefits

USS (United States Standard) flat washers are thicker, have larger outside diameters and do not fit as tightly around bolts as SAE (Society of Automotive Engineers) washers.
Steel is strong and durable but less corrosion resistant than stainless steel. To improve its resistance to corrosion, it may receive additional finishes and coatings.
