I've been buying from Military Fasteners for about 2 years. In that time, I don't ever recall having a bad experience. Please keep up the great work and continue offering the fair prices, fast shipping and excellent customer service.

Dependable! I KNOW that my orders with military fasteners will go out the same day and that the rare backorder will be shipped without my having to follow up.

Military Fasteners did an excellent job fulfilling my most recent order. This superior performance is typical for ACS. My order arrived in excellent condition within just 3 days of placing the order. Well done!
