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

The competition cancelled my order saying it could not be shipped. Very impressed with the service. Military Fasteners will be the first people I call in future:)

I would like to thank Military Fasteners for their accurate speedy delivery of hardware. Many people don’t realize that when an aircraft is grounded that schedules cannot be met. Their attention to being timely for a $36 dollar purchase made an airplane ready within two days.
