- Reliable thickness tolerance (2.4-3.6mm) ensures consistent performance and secure fastening in repetitive assembly applications.
- Full compliance with stringent environmental regulations, including RoHS 3 and REACH, for safe use in global markets and eco-conscious industries.
- Metric system compatibility simplifies sourcing and integration with other M8 metric components, reducing installation time.
- Durable, non-galling surface maintains integrity under pressure, extending service life in high-vibration settings.
Professional Applications & Engineering Value
This M8 flat washer is engineered to address common industrial challenges such as corrosion-induced failure and uneven load distribution. Made from 18-8 stainless steel, it offers superior resistance to rust and oxidation, making it suitable for outdoor machinery, chemical processing equipment, and marine applications. The DIN 440-R specification ensures precise metric dimensions (28mm OD, 9mm ID) that provide a stable bearing surface, reducing stress on connected parts and minimizing the risk of fastener fatigue. Its flat washer design is ideal for distributing clamp load evenly, protecting surfaces from damage, and maintaining bolt tension in industrial assemblies, thereby enhancing overall structural reliability and reducing maintenance costs.
Specification Summary & Compliance
This washer conforms to DIN 440-R standards with an inner diameter of 9 mm, outer diameter of 28 mm, and thickness ranging from 2.4 to 3.6 mm, designed for M8 screw sizes in metric applications. It is manufactured from 18-8 stainless steel and complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and adherence to international industrial requirements.
