The NAS1149F0516P Washer is a precision aerospace flat washer manufactured to National Aerospace Standard (NAS) specifications for aircraft and industrial fastening applications. Designed to distribute clamping force evenly under bolts, screws, and nuts, this washer helps reduce surface damage, maintain alignment, and improve fastening reliability in vibration-sensitive environments.

The “P” designation generally identifies cadmium-plated steel construction, providing corrosion resistance and long-term durability for aviation maintenance and assembly operations. This product is supplied in a convenient pack of 100 pieces for workshop, maintenance, and production use.

Its primary features include:
Manufactured to NAS1149 aerospace hardware standards
Precision flat washer for aircraft fastening systems
Helps distribute load and reduce fastener-related wear
Cadmium-plated steel construction for corrosion protection
Suitable for structural and mechanical aviation applications
Packaged in a 100-piece maintenance and assembly pack
Compatible with aircraft repair and overhaul procedures

Washers like the NAS1149F0516P are widely used in aerospace assemblies because they improve joint stability, protect component surfaces, and help maintain secure fastening performance under operational vibration and mechanical stress.
