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.

Recently my avionics technician and I were installing a component in my aircraft and there were some critical fasteners missing from the manufactures package. This stopped the entire process. I called Military Fasteners after finding the parts on line, and Trisha answered the phone. I told her the situation and that I needed them ASAP. I found the parts gave her the part number and she confirmed they were in stock. This was about 430 in the afternoon just before closing. Trisha was kind and professional got the parts out the door that evening even though it was after the shipping cut off. Saved the day. I can tell you this entire company is represented by Trisha, anything they can do to help you out of a jamb they will absolutely go the extra mile and Trisha is the go to person. I am sure there are others there with her same attitude and professionalism. This is a great resource for all your fasteners needs.

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!

After an extensive look for parts, Ramona Real of Military Fasteners was the one that could help in finding what I needed and provide the necessary paperwork to go with it. Shipping on time and packing perfect. Good people to work with and highly recommended A+++++
