Professional Applications & Engineering Value
These nylon plastic flat washers deliver critical engineering solutions where electrical insulation and corrosion resistance are paramount. The white nylon material provides excellent dielectric properties while resisting chemicals, moisture, and environmental degradation. Engineered to NAS1515-H7L standards, these washers meet rigorous aerospace requirements while serving automotive assemblies, industrial equipment, and electronic enclosures. The precise 0.453" ID x 0.75" OD dimensions ensure perfect fitment for 7/16" screw size applications, preventing loosening under vibration. Their non-metallic composition eliminates galvanic corrosion when used with aluminum or other dissimilar metals, extending equipment service life in demanding environments.
Specification Summary & Compliance
Manufactured to NAS1515-H7L specifications with inch system dimensions: 0.453" inner diameter, 0.75" outer diameter, and thickness ranging 0.021-0.041". These flat washers are RoHS 3 (2015/863/EU) compliant and meet REACH (EC 1907/2006) standards for substance restrictions. The nylon construction provides reliable performance across a temperature range up to 180°F maximum, making them suitable for various industrial and aerospace applications requiring precise dimensional tolerances and material consistency.
