Trisha Hawkins is the best! Very helpful!

Products are military grade MIL-SPEC as advertised. I was able to locate #10 locking counter-sunk nutplates when ALL other locations, including Aircraft-Spruce, could not supply.

Excellent variety, quality, and service. And, small orders are no problem. Military Fasteners is a tinker's delight and a great resource. I also appreciate their using the USPS. So many companies ship UPS only and to Alaska the UPS price is ridiculous. Thank you.
