Small order but all was in stock, sales rep was very friendly and made it a pleasure. Shipped and received quicker than expected.

4.0

I have been restoring a 1946 Globe Swift over the past year and have relied heavily on Military Fasteners to supply both AN hardware and some aircraft specific parts. The service has been excellent, the expertise in answering some of my questions invaluable. Military Fasteners is my go-to for all my aircraft needs. Thank you all very much.

4.5

Parts were described exactly as received. Delivered exactly as promised. I was treated better than could have been expected. Give a 5.5 stars out of 5.

5.0

Military Fasteners is an exceptional company in terms of how they run their business. Very prompt and responsive to questions, concerns, quotes, and all other forms of inquiry. Brittany Cornish supports many of the business transactions we perform with Military Fasteners and has made working with them an absolute pleasure. I would highly recommend them to anyone seeking mil-spec hardware.
