Professional Applications & Engineering Value

This heavy-duty flat washer is engineered to solve critical challenges in industrial fastening. The 18-8 stainless steel material provides excellent corrosion resistance, making it suitable for applications exposed to moisture, chemicals, and varying temperatures, such as in construction, marine equipment, and food processing machinery. Its generous 2.5" OD effectively distributes clamping force over a wider area, which prevents embedding into softer materials and mitigates stress concentration—a common cause of joint failure. The precise 1.062" ID ensures a snug fit on 1" screws, minimizing play and vibration-induced loosening. By adhering to the ASME B18.21.1 specification, this washer delivers predictable performance, reduces maintenance downtime, and enhances the overall integrity of your mechanical assemblies.
