The AN960-416L Washer is a lightweight aerospace flat washer manufactured to Army-Navy (AN) specifications for use in aircraft fastening systems. The “L” designation indicates a reduced-thickness, light-duty configuration designed for applications where weight savings and close assembly tolerances are important.

This washer is used to distribute load under nuts and bolt heads, reduce surface wear, and help maintain proper alignment in aircraft structural, mechanical, and interior assemblies. It is supplied in a 100-piece pack for maintenance, repair, and production operations.

Its primary features include:
Manufactured to AN960 aerospace standard specifications
Lightweight “L” series reduced-thickness design
Helps distribute load and reduce surface damage
Suitable for aircraft structural and mechanical assemblies
Commonly used in general aviation maintenance
Steel construction for durability and strength
Packaged in a 100-piece maintenance set
Compatible with aircraft assembly and overhaul procedures

Washers like the AN960-416L are widely used in aerospace systems because they provide reliable fastening support while reducing overall weight and ensuring precise fitment in aviation assemblies.
