Customer Reviews

Best source for mil spec hardware. Website is user friendly, inventory is expansive, overnight shipment is a huge plus, and customer support is responsive and very helpful.
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.
Military Fasteners is first on my list for the hard to find items so often associated with Government Projects. Brittany and Michael have always been quick to respond and nothing but professional in every way. I look forward to a continued relationship with Military Fasteners.
Paige Twombly is fantastic to work with! She is the definition of fast, professional and efficient!!!
