You ship them right out to me via US mail in a padded envelope. This makes you my go-to company for all my parts needs. When I've asked questions on-line about an item they are answered thoroughly and usually the same day. Thanks Military Fasteners!

I ordered 2 custom coax cable assemblies in the early afternoon, and was shocked when I was notified they shipped later that day! Great service!

Tanks for the fantastic service. I ordered over the new year period and was amazed my shipment arrived so fast, all the way to New Zealand. Less than a week and that included clearing Customs. Awesome!!
