Customer Reviews

In dealing with Military Fasteners for 3 plus years, I can honestly say Ive never had a bad experience with the company. Please keep up the great work and youll keep me coming back for as long as I am flying.
We were able to find the parts needed at a competitive price. Jasmine Morales was helpful in fulfilling this order.
I am unable to add any suggestions. Military Fasteners is an on time provider. I have never understood why the orders from you company are shipped and arrive in time given to me. Other companies say same day ship or the following day and it takes much much longer for the product to arrive. All I say, Good Job
Very good service, as usual. Order was complete and correct. It is easy to order on your website and the deliveries are always in the specified time.
