Good job, all tools accounted for, packing and delivery was great. All the tools are high quality. Thanks.

I've been a Customer since the early 90s. Never an Issue with products or Customer Service. I recently purchased a New Concord Battery, Harness and Battery Minder Charger. I clicked the wrong button and did not order the correct charger for the Concord. Called Military Fasteners when it was delivered, told the gal what I did and she said well get the right one on the way and e-mail you the Return Authorization. I sent the wrong one back and two days later the correct one arrived. A few days after that my Credit Card was reimbursed the full amount for my incorrect order. By any Business Standard, who could complain about that kind of Service!!! Keep up the Great Work...

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.
