Professional Applications & Engineering Value

This nylon plastic flat washer delivers critical engineering solutions where metal washers fail. The Nylon material provides inherent electrical insulation, making it ideal for electrical enclosures, control panels, and electronic assemblies where current isolation is paramount. Its wide temperature range (-40°F to 300°F) ensures dimensional stability in both freezing outdoor applications and high-temperature industrial environments. The green color coding aids in component identification during assembly and maintenance. As a non-conductive, non-corrosive alternative to metal washers, it eliminates galvanic corrosion risks while providing consistent load distribution for No. 3 screws in precision equipment, automotive components, and consumer electronics where weight reduction and chemical resistance are valued.

Specification Summary & Compliance

This flat washer features precise dimensional specifications with 0.109" inner diameter, 0.219" outer diameter, and thickness ranging 0.022-0.028". Manufactured to ASME B18.22.1 standards for dimensional consistency and performance reliability. The product is fully RoHS 3 (2015/863/EU) compliant and REACH (EC 1907/2006) compliant (06/14/2023, 235 SVHC), meeting the latest environmental regulations for hazardous substance restrictions. The inch system measurement ensures compatibility with standard No. 3 screw applications across North American industrial specifications.
