Customer Reviews

Military Fasteners is one of my top hardware suppliers. If you can't find a mil-spec part, they will find it for you. Shipping is always fast and reliable. Kristen is phenomenal to work with. Highly recommend.
I can always count on Military Fasteners to give me the best selection of aircraft parts and supplies. Also always get fast shipping, and appreciate the USPS option that is much less expensive than the overnight shippers for us located in Southern California. Thank you for making it easier to keep our general aviation and experimental aircraft flying!
I have been doing business with Military Fasteners for a number of years. Every Time I have needed a question answered in finding something for my projects Military Fasteners has always been there. The people I talk to are helpful and knowledgeable concerning all the vintage planes I have called looking for a special item needed. Thank you for being YOU!
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.
