Professional Applications & Engineering Value
This M22 split lock washer delivers critical vibration-resistant fastening for demanding industrial applications where 18-8 stainless steel provides essential corrosion resistance. The DIN 7980 standard ensures dimensional precision and reliable performance in mechanical assemblies subjected to constant motion or thermal cycling. Engineered with a standard split lock design, it maintains constant spring tension against loosening in machinery, automotive components, and processing equipment. The metric sizing (23.5mm ID × 32.9mm OD) guarantees perfect compatibility with M22 fasteners while the controlled thickness (4.3-4.7mm) provides optimal deflection characteristics. This industrial-grade washer solves common fastening failures in high-vibration environments through its durable construction and standardized compliance.
Specification Summary & Compliance
Manufactured to DIN 7980 specifications with precise dimensional tolerances including 23.5mm inner diameter, 32.9mm outer diameter, and 4.3-4.7mm thickness range. Constructed from 18-8 stainless steel for corrosion resistance and durability. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental standards, ensuring safe use across industrial applications. Designed specifically for M22 screw sizes in metric fastening systems.
