You ship them right out to me via US mail in a padded envelope. This makes you my go-to company for all my parts needs. When I've asked questions on-line about an item they are answered thoroughly and usually the same day. Thanks Military Fasteners!

5.0

I have ordered from Military Fasteners for years and have never had a complaint! And do not expect to have a complaint in the future.

4.0

Products are military grade MIL-SPEC as advertised. I was able to locate #10 locking counter-sunk nutplates when ALL other locations, including Aircraft-Spruce, could not supply.

5.0

Great service when calling in orders, very knowledgeable staff. The web site is also very user friendly for ordering and shipping is quick. I give it a 5 star rating.
