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 worked with Isaac Beltran and he did a great job and rare to find.....someone with attention to detail.
I am unable to add any suggestions. Military Fasteners is an on time provider. I have never understood why the orders from you company are shipped and arrive in time given to me. Other companies say same day ship or the following day and it takes much much longer for the product to arrive. All I say, Good Job
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.
