AN970 Military Washers Frequently Asked Questions
What are AN970 washers?
AN970 washers are large-OD mil-spec flat washers manufactured to Aeronautical Standard (AN) specifications. Their oversized outer diameter provides a significantly larger bearing surface than standard flat washers, making them the preferred choice for distributing load over soft or composite materials in military and aerospace assemblies.
When are AN970 washers used instead of AN960 washers?
AN970 washers are used when the material being fastened requires a larger bearing surface to prevent pull-through or crushing, such as wood, composites, or thin sheet materials. AN960 is the general-purpose mil-spec flat washer; AN970 is the wide-body equivalent for load-spreading applications.
What drawing revision are AN970 washers manufactured to?
Superior Washer AN970 washers are manufactured to NASM970 REV 2.
Are your AN970 washers made in the USA with DFARS-compliant materials?
Yes. All AN970 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.
