I placed an order with Lindsey at Military Fasteners late afternoon, 3:15 to be exact and she was nice enough to expedite my order and made sure to get it shipped that day. Great company with great people.

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