Professional Applications & Engineering Value
This nylon flat washer delivers critical engineering solutions where metal washers fail. The white nylon plastic construction provides inherent corrosion resistance, eliminating galvanic corrosion issues in mixed-material assemblies. Its excellent dielectric properties make it ideal for electrical insulation applications in control panels, junction boxes, and electronic enclosures. The precise 0.328" ID ensures secure fitment with 5/16" screws while the flat washer design distributes clamping force evenly, preventing surface deformation in soft materials. With 180°F temperature resistance, this washer maintains dimensional stability in automotive, aerospace, and industrial equipment exposed to moderate heat, while complying with rigorous NAS1515-H5H specifications for consistent quality.
Specification Summary & Compliance
This flat washer features precise inch system dimensions with 0.328" inner diameter, 0.562" outer diameter, and thickness ranging 0.084-0.104".
