Professional Applications & Engineering Value
This nylon flat washer delivers critical engineering solutions where metal washers fail. The white nylon plastic material provides inherent corrosion resistance, making it ideal for chemical processing, marine, and outdoor applications where moisture and corrosive agents degrade metal components. Its electrical insulation properties secure sensitive electronic assemblies and prevent galvanic corrosion between dissimilar metals. The precise 0.765" ID and 1.312" OD dimensions ensure optimal load distribution for 3/4" screw applications, while the controlled thickness variation maintains consistent clamping force. Operating effectively up to 180°F, this washer serves reliably in automotive, aerospace, and industrial equipment where temperature fluctuations and regulatory compliance are paramount concerns.
Specification Summary & Compliance
Manufactured to NAS1515-H12H aerospace specifications with inch system dimensions: 0.765" inner diameter, 1.312" outer diameter, and 0.084-0.104" thickness range. This flat washer demonstrates full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use in regulated industries. The nylon construction meets precise dimensional tolerances required for 3/4" screw applications while providing consistent performance across the specified temperature range.
