Professional Applications & Engineering Value

This external tooth lock washer addresses critical vibration-induced fastener failure in demanding industrial applications. The zinc-plated steel construction provides essential corrosion resistance while maintaining the mechanical properties needed for high-stress environments. External teeth configuration ensures maximum biting action into both the fastener head and mounting surface, creating a positive locking mechanism that outperforms standard flat washers in vibration-prone assemblies. Engineered specifically for No. 2 screw sizes with precise 0.086" ID and 0.195" OD dimensions, this component delivers reliable performance in electrical enclosures, precision instruments, automotive components, and machinery where vibration resistance is paramount. The combination of Rockwell C40 hardness and optimized tooth geometry maintains locking force through thermal cycling and mechanical shock.

Specification Summary & Compliance

This external tooth lock washer features inch system dimensions with 0.086" internal diameter, 0.195" outer diameter, and thickness ranging 0.010-0.016". Manufactured from zinc-plated steel with Rockwell C40 hardness rating, the component provides consistent mechanical properties and corrosion protection. The washer complies with RoHS 3 (2015/863/EU) restrictions on hazardous substances and REACH (EC 1907/2006) regulations concerning chemical substances, ensuring environmental compliance for international markets. External tooth configuration follows industry-standard locking washer principles for maximum anti-rotation performance in fastener assemblies.
