I was very pleased with the processing of my order from Military Fasteners. Placed my order very late on Thursday. Confirmation was immediate and received a tracking number the next day. It was delivered on the Monday. Excellent service from Military Fasteners

The only hardware supplier that rushes to ship your order. Placed an order at 4pm, and they got it out same day.
