Customer Reviews

Military Fasteners was recently added to our list of approved vendors and so far it has been an absolute pleasure working with them. The speed, communication, and coordination with our orders so far have been absolutely above and beyond. Sarah is an absolute all star and made the ordering process quick and seamless. 10/10 Would recommend to anyone looking for products!
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.
prompt service and delivery and fair pricing ... can't ask for more than that!
The products sent allowed the repair to be completed in a timely manner. Thank you for Military Fasteners being there and having parts available to allow our vintage aircraft to continue flight.
