Ordering is easy, prices are generally the best around, and now that USPS is a shipping option, everything is good!

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

Another good experience with Military Fasteners, and our Sales Rep, Dan Hunter. We needed hardware for an older aircraft model, and Dan's expertise was exceptional. He quickly identified fasteners, even for parts with unclear descriptions, and provided invaluable technical assistance. The supporting data was spot-on, verified by our technicians. Despite finding slightly lower prices elsewhere, the unmatched service and expertise from Military Fasteners, particularly Dan, make them our preferred choice. Our order was delivered ahead of schedule. Highly recommend MilFast for top-notch service and technical support!
