The NAS1149DN832J Washer is a precision aerospace flat washer manufactured to National Aerospace Standard (NAS) specifications for aircraft fastening and structural assembly applications. This washer is commonly used as an alternative to the AN960JD8 series and is designed to provide reliable load distribution, spacing, and surface protection in aviation hardware installations.

The “DN” designation typically identifies an aluminum alloy construction, while the “J” suffix indicates a thinner-profile configuration used where reduced weight and limited clearance are important considerations in aircraft assemblies. Supplied in a pack of 100 pieces, these washers are suitable for maintenance inventory, production, and repair operations.

Its primary features include:
Manufactured to NAS1149 aerospace hardware standards
Alternative to AN960JD8 aircraft washer specification
Lightweight aluminum alloy construction
Thin-profile (“J”) configuration for reduced clearance applications
Helps distribute fastener load and reduce surface wear
Suitable for aircraft structural and mechanical assemblies
Packaged in a convenient 100-piece maintenance pack
Compatible with aviation repair and overhaul procedures

Washers like the NAS1149DN832J are widely used throughout aerospace systems because they help maintain fastening integrity, minimize structural stress concentrations, and support lightweight aircraft assembly design requirements.
