• Precise dimensional compatibility with 14.7mm ID perfectly matching M14 screw applications
• Reliable locking performance engineered to DIN 7980 standards for consistent quality
• Durable mechanical properties with 2.8-3.2mm thickness providing optimal spring action
• Environmental compliance assurance meeting RoHS 3 and REACH regulations for global supply chains
• Optimized outer diameter at 21.1mm ensuring proper bearing surface distribution

Professional Applications & Engineering Value

This M14 split lock washer delivers critical engineering value in applications where vibration-induced loosening compromises assembly integrity. The 18-8 stainless steel construction provides exceptional corrosion resistance for outdoor equipment, marine applications, and chemical processing facilities where environmental factors degrade ordinary fasteners. The split lock design creates continuous spring tension that counters rotational forces in machinery, automotive components, and structural assemblies. Manufactured to DIN 7980 specifications, this metric lock washer maintains precise dimensional tolerances for reliable performance in high-cycle manufacturing environments. The combination of material durability and mechanical locking action makes it ideal for maintenance-critical applications where disassembly for retightening would cause operational downtime.

Specification Summary & Compliance

This standard split lock washer features precise dimensions of 14.7mm internal diameter and 21.1mm outer diameter with thickness ranging 2.8-3.2mm. Manufactured in compliance with DIN 7980 standards for dimensional accuracy and performance requirements. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental responsibility and chemical safety in industrial applications.
