Professional Applications & Engineering Value

Engineered for demanding industrial applications, these nylon plastic flat washers solve critical challenges in electrical, automotive, and machinery assemblies. The 0.141" ID provides precise alignment with No. 5 screws, preventing thread damage and ensuring uniform clamping force. With a temperature range of -40°F to 180°F, these washers maintain dimensional stability in both freezing and elevated temperature environments. The nylon material offers inherent corrosion resistance, making them ideal for chemical exposure and outdoor applications where metal washers would degrade. Their electrical insulation properties prevent galvanic corrosion between dissimilar metals and protect sensitive electronic components from current leakage, while the Rockwell R115 hardness ensures long-term performance under vibration and cyclic loading conditions.

Specification Summary & Compliance

This flat washer features precise inch system dimensions with 0.141" inner diameter and 0.406" outer diameter, manufactured to standard washer specifications for No. 5 screw applications. The component maintains consistent 0.035-0.045" thickness tolerance across all production batches. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations ensures environmental safety and unrestricted use in international markets. The nylon plastic construction meets industry standards for non-conductive, non-magnetic washers in electrical and precision mechanical assemblies.
