Professional Applications & Engineering Value
This Nylon flat washer delivers critical engineering solutions where electrical insulation and corrosion resistance are paramount. The white nylon plastic construction prevents galvanic corrosion between dissimilar metals, making it ideal for marine, chemical processing, and outdoor applications. Its non-conductive properties ensure safety in electrical enclosures and electronic assemblies, while the precise 0.328" ID x 0.562" OD dimensions provide reliable seating for 5/16" screws. The material's inherent lubricity reduces friction during installation, preventing damage to sensitive surfaces. Engineered to meet NAS1515-H5L specifications, this washer maintains dimensional stability across temperature variations up to 180°F, ensuring long-term reliability in demanding industrial environments.
Specification Summary & Compliance
This flat washer features precision dimensions with 0.328" inner diameter and 0.562" outer diameter, designed specifically for 5/16" screw applications in the inch measurement system. Manufactured in compliance with NAS1515-H5L aerospace specifications, ensuring consistent quality and performance. The product is fully RoHS 3 (2015/863/EU) compliant and REACH (EC 1907/2006) compliant with current SVHC requirements as of June 14, 2023. Temperature rating certified for continuous operation up to 180°F maximum.
