Any time I need anything it is here when I need it without question. I have tried other suppliers and ship dates are not honored sometimes it can take two weeks for item in their stock!! Thanks for being consistent and prompt.

Ordered the plugs on Tuesday and received them Friday morning. Great service. Items arrived as ordered. You run a tight ship.

As always great service with fast shipping. That's why I always choose military fasteners first for my aircraft needs. Thanks.

I have been a customer since Fullerton Air Parts (Flo Irwin). That should speak volumes of the service I have received from Military Fasteners. In the early days, I had a variety of planes and was based out of Orange County Airport. At the time, the airport was surrounded by bean fields. I, and some of my friends, would frequently fly into Fullerton airport for lunch, the pick up whatever supplies we needed from Flo. She was a great lady, and I am glad that she passed on such a wonderful legacy. I am certain that she would be very proud of what she started, and proud of you all for building on her meager beginnings.
