Professional Applications & Engineering Value

These SAE flat washers in 18-8 stainless steel provide critical engineering solutions where corrosion resistance and dimensional precision are paramount. The 1.5" inner diameter precisely accommodates 1 3/8" screws while the 2.75" outer diameter creates an optimal load-bearing surface that prevents surface damage and distributes pressure evenly. Ideal for industrial applications including machinery assembly, structural fastening, and commercial equipment, these washers address common challenges like galvanic corrosion, surface marring, and fastener loosening. The stainless steel construction ensures reliable performance in humid, chemical, or outdoor environments where carbon steel washers would fail, making them essential for maintenance-critical installations and long-term reliability.
