Professional Applications & Engineering Value
This nylon self-retaining washer delivers critical engineering solutions where traditional metal washers fail. The Rockwell R120 hardness provides exceptional abrasion resistance while the self-retaining feature eliminates the need for additional locking components, streamlining assembly processes. Perfect for electrical enclosures, automotive components, and precision instrumentation, this washer prevents short circuits and galvanic corrosion while maintaining secure fastening across the broad -40°F to 180°F temperature range. The nylon plastic construction offers excellent chemical resistance and electrical insulation properties, making it ideal for harsh industrial environments where reliability is paramount.
Specification Summary & Compliance
Manufactured to precision dimensions with 0.115" inner diameter and 0.203" outer diameter, this washer maintains consistent performance across both inch (No. 2) and metric (M2) screw systems. The Rockwell R120 hardness ensures dimensional stability under load, while the material thickness range of 0.022-0.042" provides optimal compression characteristics. Fully compliant with RoHS 3 (2015/863/EU) environmental standards, this component meets international regulatory requirements for restricted substances, making it suitable for global supply chains and environmentally conscious manufacturing operations.
