Professional Applications & Engineering Value

These 18-8 Stainless Steel flat washers are engineered to address common industrial challenges, such as corrosion-induced failures and inconsistent load bearing. The stainless steel composition provides excellent resistance to rust and chemicals, making them suitable for outdoor, marine, and chemical processing environments. With a precise 1.25" outer diameter and 0.156" inner diameter, they ensure a snug fit for No. 6 screws, preventing loosening under vibration and distributing pressure evenly to protect surfaces. This design minimizes stress concentrations, reduces maintenance downtime, and enhances the longevity of assemblies in industrial washers applications, from machinery to structural frameworks, where reliability and corrosion resistance are critical.

Specification Summary & Compliance

This flat washer adheres to standard inch measurement tolerances, with an inner diameter of 0.156" and outer diameter of 1.25", designed specifically for No. 6 screw sizes. It is manufactured from 18-8 Stainless Steel, ensuring consistent performance without a rated hardness for general use. The product complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming it is free from hazardous substances and meets environmental safety requirements for industrial and mechanical applications.
