Frequently Asked Questions
What is the difference between USS and SAE flat washers?
USS (Type B) flat washers have larger outside diameters and are thicker than SAE (Type A) washers of the same bolt size. USS is designed for softer materials and larger load distribution. SAE is used for harder materials and standard fastener installation.
How corrosion-resistant is this stainless steel fastener?
Stainless steel fasteners resist rust and corrosion in most environments. For specific corrosion requirements, consult our engineering team or the appropriate ASTM specification.
