Professional Applications & Engineering Value

This M5 internal tooth lock washer delivers critical vibration-proof security for demanding industrial applications where fastener failure is not an option. The 18-8 stainless steel construction provides excellent corrosion resistance, making it ideal for automotive assemblies, machinery components, and industrial equipment exposed to moisture, chemicals, or outdoor elements. The internal tooth configuration according to DIN 6797 ensures positive locking action by digging into both the bearing surface and fastener head, effectively resisting rotational forces and vibration-induced loosening. This design solves common engineering challenges in high-vibration environments like engine compartments, rotating machinery, and transportation equipment, where traditional flat washers or external tooth designs may compromise performance. The precise 5.3mm ID and 10mm OD dimensions provide optimal contact area while maintaining space efficiency in compact assemblies.
