Professional Applications & Engineering Value
This nylon flat washer delivers critical engineering solutions where electrical insulation and corrosion resistance are paramount. The white nylon plastic material provides excellent dielectric properties, making it ideal for aerospace avionics, electronic enclosures, and industrial control systems where electrical isolation prevents system failures. The NAS1515-H04L standard compliance ensures precise dimensional control and reliability in high-vibration environments. With its non-conductive properties, this washer eliminates galvanic corrosion risks when used with dissimilar metals, extending equipment lifespan in demanding industrial applications while maintaining consistent performance across the specified temperature range.
Specification Summary & Compliance
This flat washer features precise inch system dimensions: 0.125" inner diameter, 0.312" outer diameter, and thickness ranging from 0.021" to 0.041". Manufactured to meet NAS1515-H04L specifications for aerospace applications, it ensures dimensional accuracy and performance consistency. The product is fully RoHS 3 (2015/863/EU) compliant and meets REACH (EC 1907/2006) requirements, including the latest SVHC updates. Designed specifically for No. 4 screw size applications, this washer operates effectively within a temperature range up to 180°F maximum.
