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.

Hello, I am an Estimator for CAMCO Mfg. Inc. We work with many Prime companies that require Military Fasteners. Kristen Belmont is always the first to respond and gives me great service! She guides me with her knowledge and treats me w/much respect (even when I don't know what I'm talking about) Out of all the outside sources I have to work with, I enjoy working with her best! Rick Donahue CAMCO Mfg. Inc.

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!
