Professional Applications & Engineering Value

Engineered for demanding industrial applications, these rectangular washers provide critical solutions where standard round washers fall short. The 18-8 stainless steel composition delivers excellent corrosion resistance in chemical processing, marine, and outdoor environments, while the Rockwell B90 hardness ensures the washer maintains its structural integrity under sustained pressure and vibration. The rectangular footprint (1.25" x 0.625") distributes load over a larger surface area, preventing material deformation and reducing stress concentration in assemblies using 1/4" fasteners. This makes them ideal for structural steel connections, heavy machinery, and precision equipment where corrosion resistant washers must maintain dimensional stability and clamping force over extended service life.
