• High hardness (Rockwell C42) provides excellent durability and maintains spring action over repeated use
• Precise conical design delivers consistent axial tension to prevent loosening from shock or vibration
• Metric M18 screw compatibility offers seamless integration with standard industrial fastener systems
• Full compliance with DIN 6796 guarantees dimensional accuracy and reliable performance in demanding applications
• RoHS 3 and REACH compliance ensures environmental safety and regulatory acceptance for global supply chains
• Robust steel construction provides corrosion resistance and long-term reliability in harsh operating conditions

Professional Applications & Engineering Value

This spring lock washer delivers critical engineering value by solving persistent loosening issues in vibration-prone industrial applications. The conical shape and high-carbon steel material work synergistically to maintain constant tension between fastened components, effectively countering rotational forces that cause conventional fasteners to fail. Particularly valuable in heavy machinery, automotive assemblies, and power transmission systems, this DIN 6796 compliant washer provides predictable spring characteristics that engineers can rely on for critical connections. The precise 19mm ID and 42mm OD dimensions ensure perfect fit with M18 fasteners while the controlled hardness (Rockwell C42) balances flexibility with structural integrity, making it ideal for applications where both vibration damping and reusability are required.

Specification Summary & Compliance

Manufactured to DIN 6796 specifications with precise dimensional tolerances including 19mm internal diameter, 42mm outer diameter, and 4.5mm thickness. The conical spring lock washer features Rockwell C42 hardness for optimal spring performance. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental responsibility and chemical safety in industrial applications worldwide.
