My experience in doing business with Military Fasteners through Trisha Hawkins is nothing short of GREAT! She is knowledgeable, attentive to detail and very helpful. This makes my purchase a lot easier and faster lead time. She is an asset to Military Fasteners.

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.

I have been doing business with Military Fasteners for a number of years. Every Time I have needed a question answered in finding something for my projects Military Fasteners has always been there. The people I talk to are helpful and knowledgeable concerning all the vintage planes I have called looking for a special item needed. Thank you for being YOU!
