SAE A2 18-8 Stainless Steel Flat Washer (Fractional)
SAE A2 (18-8) Stainless Steel Flat Washers for Precision Fastening
SAE A2 (18-8) stainless steel flat washers are precision-manufactured fasteners built to meet strict SAE (Society of Automotive Engineers) dimensional standards. Designed for applications where strength, corrosion resistance, and accurate fitment are essential, these washers are widely used in automotive assemblies, industrial machinery, construction equipment, and precision mechanical systems. Their dependable performance makes them a go-to choice for professionals who require long-term reliability in demanding environments.
Material Benefits of A2 (18-8) Stainless Steel
Superior Corrosion Resistance
A2 stainless steel, commonly known as 18-8 stainless steel, contains approximately 18% chromium and 8% nickel. This composition provides excellent resistance to rust, oxidation, and mild chemical exposure. SAE A2 stainless steel flat washers perform exceptionally well in humid, damp, and outdoor conditions, making them suitable for both interior and exterior applications.
Strength and Durability
In addition to corrosion protection, 18-8 stainless steel offers strong mechanical properties and consistent performance under load. These washers resist deformation while maintaining structural integrity, helping preserve bolt preload and joint stability over time.
SAE Dimensions for Accurate Fit
SAE flat washers are manufactured with smaller outside diameters and tighter tolerances compared to USS washers. This precision sizing ensures proper alignment in assemblies where space is limited or where exact fastener fit is required. By evenly distributing the load from bolts, screws, and nuts, SAE A2 stainless steel flat washers prevent surface damage, reduce embedding, and extend the life of the fastening system.
Common Applications
SAE A2 (18-8) stainless steel flat washers are ideal for automotive components, aerospace systems, manufacturing equipment, and light structural assemblies. Their corrosion-resistant construction and dimensional accuracy make them a versatile, cost-effective fastening solution for professionals who demand strength, precision, and long-lasting performance.
