S-95647A115 0.14" ID x 0.41" OD Plastic Washers

Key Features & Benefits at a Glance

• Superior chemical and moisture resistance from Delrin® Acetal Plastic material prevents corrosion and degradation in harsh environments
• Excellent dimensional stability maintains precise 0.14" ID and 0.41" OD for consistent performance with No. 5 screws
• Optimized load distribution with controlled 0.030-0.050" thickness range prevents surface damage and extends assembly life
• Reliable hardness performance at Rockwell R120 ensures long-term wear resistance and mechanical integrity
• Enhanced thermal capability withstands temperatures up to 180°F for demanding industrial applications
• Full regulatory compliance with RoHS 3 and REACH standards ensures safe use across global markets
• Low friction properties reduce galling and provide smooth assembly operations

Professional Applications & Engineering Value

These Delrin® Acetal Plastic flat washers deliver exceptional engineering value in applications where metal corrosion, electrical conductivity, or chemical compatibility are primary concerns. The white plastic construction offers excellent visibility for quality control while providing natural lubrication that eliminates the need for additional lubricants. Engineered specifically for No. 5 screws in inch system applications, these washers solve critical challenges in electrical equipment, food processing machinery, and medical devices where non-conductive, non-marring components are essential. The material's inherent low moisture absorption and dimensional stability ensure consistent performance in humid environments, while the 180°F temperature resistance makes them suitable for automotive under-hood applications and industrial equipment operating in elevated temperature conditions.

Specification Summary & Compliance

This flat washer features precise inch system dimensions with 0.14" inner diameter, 0.41" outer diameter, and thickness ranging from 0.030" to 0.050" for No. 5 screw applications. Manufactured from Delrin® Acetal Plastic with Rockwell R120 hardness rating, the product maintains consistent mechanical properties across its operating temperature range up to 180°F. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations ensures environmental safety and unrestricted use in international markets, meeting the stringent requirements of industrial and commercial applications.
