Military Fasteners never fails to have exactly what I am looking for and at a great price as well. Their quick turnaround allows me to have what I order in hand before my deadlines. Would definitely recommend them every time.

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!

I called the customer service line just before Air Venture at Oshkosh to find out if they would have the parts I needed at their booth. The service rep on the phone was very helpful and was able to check the inventory that was taken to Oshkosh.I was told that the parts would not be available but could be shipped from the warehouse without delay. I ordered a full set of intake seals for a Continental 085 on the spot and they arrived in a few days. I am very happy with the service provided, and will be ordering more parts soon! Thank you Larry

Very fast delivery and always getting what I ordered. Never had an issue with the few returns I've had. They have been very friendly and helpful.
