I am a retired AME/Pilot. I have been restoring a 1946 Globe Swift and have relied on the support and expertise provided by your sales staff. My experience has been very positive. In return, I buy everything I can from Military Fasteners. You are my preferred supplier. Thank you.

Props to my saleslady (whose name I have sadly forgotten) for her can do attitude. Fast and efficient yet friendly and thorough. The items arrived nicely padded with brown paper. Im so happy youve stopped using those hard-to-dispose-of styrofoam peanuts. Fast to ship reasonable prices. Just excellent all around!
