The NAS1149F0963P Washer is a precision aerospace flat washer manufactured to National Aerospace Standard (NAS) specifications for use in aircraft structural and mechanical fastening applications. This washer is commonly installed with bolts, screws, and nuts to distribute load evenly, reduce surface wear, and improve fastening stability in high-vibration environments.

The “P” suffix typically indicates cadmium-plated steel construction, providing enhanced corrosion resistance for aviation and industrial use. Supplied as a pack of 100 pieces, these washers are suitable for maintenance stock, assembly operations, and aircraft repair work.

Its primary features include:
Manufactured to NAS1149 aerospace hardware standards
Precision flat washer for aviation fastening systems
Helps distribute clamping load and reduce surface damage
Cadmium-plated steel construction for corrosion resistance
Suitable for aircraft structural and mechanical assemblies
Packaged in a convenient 100-piece quantity
