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.

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.
