NAS Washers

NAS flat washers are used in military assemblies to support and spread a load across the area of a mil-spec screw and MS nut to prevent pull through during normal operations. Like standard flat washers, NAS washers feature a hole in the center to improve stress distribution and can be used as spacers, vibration reducers, and more.

BW Industrial Sales is your full-service supplier for any mil-spec hardware need. All our NAS washers and other mil-spec fasteners are made in the USA to ensure USA quality, and free manufacturer’s certifications are available with every order. We work hard to make sure you have the bulk components you need to complete critical assemblies used to keep our nation safe, secure, and efficient.

What is a NAS Washer?

NAS washers are manufactured to National Aerospace Standards (NAS), generally using a smaller outside and inside diameter than standard options to provide a tighter fit in mil-spec assemblies. As NAS washers are most often used in aircraft, they are manufactured to withstand extreme temperatures, high pressures and speeds, and a variety of weight influences.

If NAS washers are not your best option, we also offer AN washers and MS washers. Regardless of your specifications or required guidelines, BW Industrial Sales has the exact mil-spec component to complete your assembly on time and without unexpected supply chain disruptions.
