S-90412A160 10.5 mm ID x 18 mm OD DIN 6797 External-Tooth Lock Washers

Key Features & Benefits at a Glance

• Superior vibration resistance with external teeth that bite into mating surfaces to prevent fastener loosening under dynamic loads
• Exceptional corrosion resistance thanks to 316 stainless steel construction, ideal for harsh environments and chemical exposure
• Precise dimensional compatibility with M10 screws through 10.5mm ID and 18mm OD for reliable fit and performance
• Guaranteed standard compliance with DIN 6797 specifications ensuring consistent quality and interchangeability
• Optimized spring action from 0.8-1.0mm thickness providing consistent tension and secure locking
• Regulatory compliance assurance meeting RoHS 3 and REACH standards for safe use in regulated industries
• External tooth design advantage offering maximum surface contact and superior grip compared to internal tooth variants

Professional Applications & Engineering Value

Engineered for demanding industrial environments, these M10 external tooth lock washers provide critical vibration resistance in machinery, automotive assemblies, and structural applications where dynamic loads threaten fastener integrity. The 316 stainless steel material offers superior corrosion resistance against chemicals, saltwater, and industrial atmospheres, significantly extending service life in harsh conditions. The external tooth configuration ensures maximum biting action into both the fastener head and base material, creating a mechanical lock that maintains clamping force where standard washers fail. This DIN 6797 compliant solution addresses common engineering challenges of maintenance reduction and joint reliability in vibration-prone applications, delivering predictable performance across temperature variations and load cycles.
