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.

Excellent service all round. The parcel arrived on my doorstep, in a regional Australian town, on the morning of the fifth day after placing my order.

As usual Military Fasteners did a great job getting the items I ordered to me here in Arizona. My last order had one item on Back Order but was sent in a timely manner direct from the manufacturer. Great Company, great service.
