Professional Applications & Engineering Value

This M18 internal tooth lock washer delivers critical vibration-resistant fastening solutions for demanding industrial applications. The 18-8 stainless steel construction provides exceptional corrosion resistance in chemical processing, marine, and food industry environments where moisture and corrosive agents are present. The internal tooth configuration ensures maximum biting action into both the bolt head and mating surface, creating a mechanical lock that maintains preload in high-vibration equipment such as motors, pumps, and heavy machinery. Manufactured to DIN 6797 standards, this washer offers predictable performance and reliable locking force retention, making it an essential component for maintenance and assembly operations where fastener security is paramount. The precise 19mm internal diameter ensures perfect fitment with M18 fasteners, eliminating play and ensuring uniform load distribution.
