S-96982A151 3.4 mm ID x 6.2 mm OD DIN 127B Split Lock Washers

Key Features & Benefits at a Glance

• Superior vibration resistance prevents loosening under dynamic loads, ensuring long-term joint integrity
• Zinc yellow-chromate plating provides excellent corrosion protection in harsh industrial environments
• Rockwell C44 hardness maintains spring tension and shape memory through repeated loading cycles
• Precision DIN 127B compliance guarantees consistent performance and interchangeability in metric assemblies
• Optimized 3.4mm ID/6.2mm OD dimensions ensure perfect fit with M3 fasteners without binding or misalignment
• RoHS 3 compliance meets international environmental standards for sustainable manufacturing
• 0.7-0.9mm thickness range provides ideal spring force while accommodating surface variations

Professional Applications & Engineering Value

Engineered for demanding mechanical applications, these M3 split lock washers solve critical vibration-induced loosening problems in industrial machinery, automotive assemblies, and electrical enclosures. The zinc yellow-chromate plated steel construction delivers dual protection against corrosion and wear, while the standard split design creates continuous spring action that maintains bolt preload under extreme conditions. The Rockwell C44 hardness ensures the washer retains its locking capability through thermal cycling and mechanical stress, making it ideal for high-vibration environments where fastener security is paramount.
