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.

Military Fasteners is an exceptional company in terms of how they run their business. Very prompt and responsive to questions, concerns, quotes, and all other forms of inquiry. Brittany Cornish supports many of the business transactions we perform with Military Fasteners and has made working with them an absolute pleasure. I would highly recommend them to anyone seeking mil-spec hardware.

When I need parts or products for my aircraft, I think only of Military Fasteners! Dependably in stock, same day shipping and quality, caring employees are all literally guaranteed. I wish every vendor I deal with was anywhere close to being as consistently customer focused!
