Customer Reviews

Discovered on Wednesday evening I needed a new tire / tube. I had it in my hands Friday in time for a weekend install. Great service!!
I called in a hot order that was needed next day. It was already mid afternoon and i had already skipped the deadline for shipments that day. I spoke with Trisha, and she went out of her way to place my order and get it pulled and shipped same day. Thank you Trisha, you are the best.
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.
