In the long time that I have used Military Fasteners to provide materials and equipment in the building of two airplanes, I have yet to have a bad experience. Keep up the good work!

Trisha Hawkins has been very helpful and easy to deal with. Any rush orders or just orders in general, she makes sure I get it within the time requested.

Love the fact that you show your shipping rates prior to placing orders. Most of the time (95%) I choose USPS Priority, the least expensive
