S-95221A200 2.2 mm ID x 5 mm OD DIN 6796 Heavy-Vibration-Resistant Spring Lock Washers

Key Features & Benefits at a Glance

• Superior vibration resistance through conical spring design that maintains constant tension under dynamic loads
• Enhanced corrosion protection with black-phosphate steel coating for extended service life in harsh environments
• Precise M2 screw compatibility with 2.2mm inner diameter ensuring perfect fit and optimal load distribution
• Reliable spring action with 5mm outer diameter providing consistent locking force throughout thermal cycles
• Industry-standard compliance with DIN 6796 specifications guaranteeing consistent performance and interchangeability
• Environmental responsibility through RoHS 3 and REACH compliance for sustainable manufacturing operations
• Space-efficient design with minimal 0.6mm overall height suitable for compact assembly applications

Professional Applications & Engineering Value

These M2 conical spring lock washers deliver critical vibration-resistant performance in demanding industrial applications where loosening under dynamic loads poses significant reliability concerns. The black-phosphate steel construction provides essential corrosion resistance for electronics, automotive, and machinery assemblies exposed to moisture or chemical environments. The conical shape creates continuous spring tension that compensates for material relaxation and thermal expansion, maintaining bolt preload where flat washers fail. Engineered to DIN 6796 standards, these metric washers ensure precise dimensional consistency for automated assembly processes while the 0.4mm thickness and compact profile make them ideal for space-constrained M2 fastener applications in precision instruments and control systems.

Specification Summary & Compliance

Manufactured to exact DIN 6796 specifications with precise dimensional tolerances: 2.2mm inner diameter, 5mm outer diameter, 0.4mm thickness, and 0.6mm overall height. These metric spring lock washers feature black-phosphate surface treatment on steel substrate and maintain full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring they meet the latest international standards for hazardous substance restrictions.
