Customer Reviews

Amelia Fato, excellent customer service. Able to provide quick response on requested quotes.
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!
Have had nothing but great experiences. If I ever need anything I just email Amelia Fato and she gets me fixed up! Super fast and helpful customer service. 10 out of 10.
I have been doing business with Military Fasteners for a number of years. Every Time I have needed a question answered in finding something for my projects Military Fasteners has always been there. The people I talk to are helpful and knowledgeable concerning all the vintage planes I have called looking for a special item needed. Thank you for being YOU!
