Any time I need anything it is here when I need it without question. I have tried other suppliers and ship dates are not honored sometimes it can take two weeks for item in their stock!! Thanks for being consistent and prompt.

4.0

This is just a note to say how much I appreciate Military Fasteners. Your prices are fair, your shipping is fast and the costs are reasonable. The paper and online catalogs have a huge assortment of products. I also like the fact that there is no minimum order.

5.0

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!

When recently ordering some barry engine mounts I found your site carried excellent technical information and the whole process went smoothly and efficiently and I was very surprised to receive the goods in question so quickly.
