The NAS1149D1416J is an aerospace-standard flat washer used in aircraft structures to distribute load under bolt or screw heads and prevent damage to mating surfaces. It is equivalent in function to AN960JD1416, and is commonly used as an approved replacement in many airframe applications.

This washer is made from aluminum alloy with a corrosion-resistant chromate or chemical conversion coating, providing a good balance of strength, low weight, and corrosion protection. It is widely used in aircraft assemblies where weight savings and surface protection are important, such as airframe structures, brackets, and equipment mounting points.

Designed to MIL/NAS specifications, it ensures consistent dimensions and reliable performance under vibration, cyclic loads, and environmental exposure typical in aviation service.
