AN961 Military Washers Frequently Asked Questions

What are AN961 washers?

AN961 washers are mil-spec countersunk flat washers manufactured to Aeronautical Standard (AN) specifications. Unlike standard flat washers, AN961 washers feature a countersunk (beveled) inner bore designed to mate with countersunk fastener heads in flush-mounting aerospace and military applications.

What applications are AN961 washers used in?

AN961 washers are used in aerospace and military structures where fasteners must sit flush with the surface. The countersunk design allows the washer to seat properly against angled bearing surfaces under countersunk screws and rivets.

What drawing revision are AN961 washers manufactured to?

Superior Washer AN961 washers are manufactured to NASM961 REV 2, the current governing specification for this series.

Are your AN961 washers made in the USA with DFARS-compliant materials?

Yes. All AN961 washers are manufactured in the United States under our ISO 9001:2015 certified QMS audited by DNV. DFARS compliance documentation and material certifications are available upon request.
