I was impressed with the speedy delivery of my order and also with the order itself.

5.0

Love the fact that you show your shipping rates prior to placing orders. Most of the time (95%) I choose USPS Priority, the least expensive

5.0

I placed an order with Lindsey at Military Fasteners late afternoon, 3:15 to be exact and she was nice enough to expedite my order and made sure to get it shipped that day. Great company with great people.

5.0

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.
