Customer Reviews

I just want to say that I am really liking what is going on with Military Fasteners. The prices, the availability of items, the fast shipping. I really like the ease of ordering online. I have been to so many websites that are confusing to say the least, but yours is easy easy to use, clear and simple. I love being able to look up all my past orders and print out the invoices if need be. I am just thoroughly impressed with everything about Military Fasteners. Keep it up and you will always be on my bookmarks bar in the number one position!
Very fast response to RFQ (less than 1 day) very competitive pricing and low MOQ requirements
