SAE A2 18-8 Stainless Steel Flat Washer (Inch)
SAE A2 (18-8) Stainless Steel Flat Washers
SAE A2 (18-8) Stainless Steel Flat Washers are precision-engineered washers designed to meet SAE (Society of Automotive Engineers) dimensional standards. Known for their corrosion resistance, strength, and reliability, these washers are widely used in automotive, machinery, construction, and industrial applications where secure fastening and long service life are critical.
Manufactured from A2 (18-8) stainless steel, these flat washers are composed primarily of chromium and nickel, providing excellent resistance to rust, moisture, and mild chemical exposure. This makes them highly versatile for both indoor and outdoor applications. The 18-8 designation is the most common stainless steel grade, offering a balance of affordability, strength, and corrosion protection, making it a dependable choice across industries.
As SAE standard washers, these components feature smaller outside diameters and tighter tolerances compared to USS (Unified Standard Series) washers. This precision sizing makes them ideal for applications requiring exact alignment, reduced surface coverage, or use with smaller fasteners. By distributing the load of bolts, screws, or nuts, SAE A2 stainless steel flat washers help prevent surface damage, improve joint stability, and extend the life of fastening systems.
These washers are especially well-suited for automotive assemblies, aerospace components, precision machinery, and equipment manufacturing. Their stainless steel construction ensures they will not easily corrode or degrade, even in environments exposed to humidity or fluctuating temperatures.
