Customer Reviews

As always, my order was filled accurately and arrived quickly. The one item not in stock in California arrived two days later from another store. Over the years, whether a large order or just a few items,I have received the same quick service. My suggestion? Continue the excellent customer service.
I am very happy with all the orders I get from Military Fasteners, very good and fast service, Very friendly staff. Thank you.
Brittany was attentive to our needs. We had to source some other products you didn't have elsewhere. We would have preferred to place an order a one place. Will come back and order another time.
Order received thanks. Easy to order online, fast response by Military Fasteners, competitive pricing and hassle free. Good job again, many thanks.
