- Enhanced durability and longevity from consistent 3.5-4.6mm thickness, reducing wear and replacement frequency
- Guaranteed interchangeability and reliability through compliance with the rigorous ASME B18.22M metric standard
- Safe for regulated industries as it is fully compliant with REACH (EC 1907/2006) environmental and health standards
- Versatile industrial application in machinery, chemical processing, and marine equipment where chemical resistance is critical
Professional Applications & Engineering Value
This M20 flat washer is engineered to address common failure points in demanding industrial settings. The core value lies in its 316 stainless steel material, which offers exceptional resistance to chlorides and acidic substances, preventing premature corrosion that can lead to joint failure. Its metric dimensions (21.9mm ID x 49.6mm OD) and controlled thickness provide a stable bearing surface, effectively distributing clamp load and preventing surface damage to assembled components. This makes it an indispensable component in industrial applications such as chemical plant equipment, offshore platforms, and food processing machinery, where equipment longevity and chemical resistance are non-negotiable for operational safety and reduced maintenance costs.
Specification Summary & Compliance
This washer conforms to the dimensional and mechanical requirements of the ASME B18.22M standard for metric flat washers. It is manufactured with a precise inner diameter of 21.9mm and outer diameter of 49.6mm, with a thickness tolerance of 3.5-4.6mm. The product is REACH (EC 1907/2006) compliant, ensuring it meets the latest European regulations on chemical substances for safe use in industrial supply chains.
