Professional Applications & Engineering Value

This M10 zinc-plated steel flat washer delivers critical engineering solutions where load distribution and corrosion resistance are paramount. Manufactured to DIN 9021 specifications, its zinc-plated steel construction provides a protective barrier against moisture, chemicals, and atmospheric exposure, significantly reducing the risk of galvanic corrosion in Class 8.8 fastener assemblies. The precisely controlled dimensions (29.7mm OD, 10.6mm ID) ensure uniform pressure distribution across bolted joints, preventing surface indentation, loosening under vibration, and premature failure in machinery, structural steelwork, and automotive applications. By maintaining clamp force and protecting substrate materials, this metric flat washer enhances the longevity and reliability of industrial equipment while supporting compliance-driven procurement.

Specification Summary & Compliance

This flat washer conforms to DIN 9021 dimensional standards with an inner diameter of 10.6 mm, outer diameter of 29.7 mm, and thickness between 2.3–2.7 mm, ensuring precise compatibility with M10 Class 8.8 fasteners. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming adherence to environmental and safety requirements for industrial components.
