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.

The products sent allowed the repair to be completed in a timely manner. Thank you for Military Fasteners being there and having parts available to allow our vintage aircraft to continue flight.
