Trisha Hawkins and her team at Military Fasteners are absolutely incredible. We do a lot of Government and Military work and due to this there are a ton of restrictions with what products we can use. I called Military Fasteners (MF) with an extremely HOT request. Trisha was able to source those part numbers, tell me they were in stock and ready to ship. I ordered these on a Wednesday at 4:00pm. They shipped the same exact Wednesday, we received that weeks Friday, even though we were guaranteed Monday/Tuesday. Trisha - THANK YOU! Trisha's Team - THANK YOU! I will only be ordering my military hardware from you all.

5.0

Military Fasteners always delivered on what I purchased. And what I returned Military Fasteners is prompt on returning it as crediting my account. I only order for myself, so I'm quite satisfied the way Military Fasteners takes care of me only as a occasional customer. Thank you Military Fasteners Personnel.

5.0

My company works directly with Military Fasteners, and we have had nothing but positive experiences. Trisha Hawkins, in particular, has been our primary contact. She always responds quickly and works to make sure the order is correct and shipped on time. Military Fasteners is a trusted vendor of ours and we look forward to working with them again in the future!

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!
