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.

You all are Awesome! I am restoring a 1946 all aluminum camper and have come to you several times for materials needed. Every time I order, I get a quality product at a fair price in a timely manner. I couldn't ask for more.

Thanks for being there for us small plane owners. It has never been cheap to own a plane but as our planes age it is getting harder and harder to find parts for upkeep. Good fast service also.
