Ramona was awesome when it came to helping me source some hard to get and not commonly used fasteners for a special project we are working on. Thanks Ramona!

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

Buying parts from Military Fasteners couldnt be easier. If I need special help I make a phone call. I can usually do it all online and get super fast service.
