• Precise dimensional accuracy with 0.095" ID and 0.2" OD for perfect fit with No. 2 screws, eliminating installation issues
• Industry-standard compliance with ASME B18.21.1 specifications, guaranteeing reliable performance in demanding applications
• Environmental regulation compliance meeting RoHS 3 and REACH standards for safe use across global markets
• Optimized thickness range (0.010-0.016") providing flexibility while maintaining consistent spring tension and locking force

Professional Applications & Engineering Value

These 400 Series Stainless Steel tooth lock washers deliver critical vibration resistance in demanding industrial applications where fastener security is paramount. The internal tooth location creates multiple biting points that dig into both the fastener and mounting surface, creating a mechanical lock that withstands extreme vibration and thermal cycling. Engineered with Rockwell C34 hardness, these washers maintain their structural integrity under repeated stress cycles without cracking or losing tension. The corrosion-resistant properties of stainless steel make them ideal for automotive assemblies, electrical enclosures, machinery, and outdoor equipment where environmental factors would compromise standard washers. The precise 0.095" ID and 0.2" OD dimensions ensure perfect compatibility with No. 2 screw size fasteners, eliminating installation errors and providing consistent performance across production runs.
