• Precise dimensional fit with 5.4mm ID and 9.2mm OD ensuring compatibility with M5 screws and consistent performance
• Standardized quality assurance by conforming to DIN 127B specifications for consistent mechanical properties and interchangeability
• Durable material construction using 18-8 stainless steel for excellent strength and long-term reliability in demanding applications
• Environmental compliance meeting RoHS 3 and REACH regulations for safe use in regulated industries
• Optimized thickness range (1.1-1.3mm) providing sufficient spring action while maintaining space efficiency in assembly

Professional Applications & Engineering Value

This M5 split lock washer delivers critical engineering value by solving common vibration-induced fastener failure in industrial equipment. The black-oxide 18-8 stainless steel construction provides superior corrosion resistance compared to plain carbon steel, making it ideal for outdoor machinery, marine components, and chemical processing equipment where moisture exposure is constant. The DIN 127B standard ensures precise dimensional control and reliable spring action that maintains clamping force under thermal cycling and mechanical stress. Engineers specify this metric lock washer for automotive assemblies, electrical enclosures, and manufacturing jigs where vibration resistance and material durability are paramount. The split design creates continuous upward force that compensates for material relaxation, preventing costly downtime from loose fasteners in critical industrial applications.
