Professional Applications & Engineering Value

These external tooth lock washers deliver exceptional engineering value in applications where vibration resistance is critical. The 18-8 stainless steel construction provides excellent corrosion resistance, making them ideal for harsh environments including marine, chemical processing, and outdoor equipment. The external tooth configuration ensures maximum gripping power by biting into both the fastener and mating surface, preventing loosening under dynamic loads. This design is particularly valuable in automotive assemblies, machinery, electrical enclosures, and industrial equipment where No. 6 screw applications require reliable, long-term fastening solutions. The combination of material strength and tooth geometry addresses common failure points in vibrating systems, extending equipment life and reducing maintenance requirements.
