- Reliable hardness performance with Rockwell C44 rating ensuring consistent spring action and fatigue resistance
- Precise dimensional compatibility with 4.5mm ID and 7.6mm OD designed for secure M4 screw fitment
- Guaranteed standard compliance meeting DIN 127B specifications for consistent quality and interchangeability
- Environmental responsibility through RoHS 3 compliance, safe for regulated industrial applications
- Optimized thickness range (0.8-1.0mm) providing ideal deflection characteristics for locking performance
Professional Applications & Engineering Value
Engineered to solve critical vibration-induced loosening in mechanical assemblies, these M4 split lock washers deliver exceptional fastening security for industrial equipment, automotive components, and machinery. The zinc yellow-chromate plated steel construction provides dual protection against corrosion and wear, while the DIN 127B standard ensures precise dimensional control for reliable performance in high-cycle applications. The Rockwell C44 hardness maintains spring tension through repeated loading cycles, preventing joint failure in critical metric fastener systems where vibration resistance is paramount for operational safety and maintenance reduction.
Specification Summary & Compliance
Manufactured to DIN 127B dimensional and performance standards with precise internal diameter (4.5mm), outer diameter (7.6mm), and thickness (0.8-1.0mm) tolerances. The split lock washer type: standard configuration ensures proper spring action and locking force. Compliant with RoHS 3 (2015/863/EU) environmental directives, making these washers suitable for global industrial applications requiring restricted substance compliance.
