• Non-conductive and non-magnetic properties make ideal for electrical and sensitive equipment applications

Professional Applications & Engineering Value

This M10 Delrin® Acetal Plastic Flat Washer delivers exceptional engineering value in demanding industrial environments where metal washers would fail. The acetal plastic construction provides inherent resistance to chemicals, fuels, and solvents while maintaining dimensional stability across temperature fluctuations. Its low moisture absorption and excellent creep resistance ensure long-term performance in applications requiring consistent clamping force. The white metric washer design is particularly valuable in food processing, medical equipment, and electrical enclosures where corrosion resistance and electrical insulation are critical. The material's natural lubricity reduces friction between components, preventing galling and simplifying maintenance in automated assembly systems. These properties make it an ideal choice for industrial plastic washers in chemical processing, automotive, and precision manufacturing applications where reliability and regulatory compliance are paramount.
