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.

I called in a hot order that was needed next day. It was already mid afternoon and i had already skipped the deadline for shipments that day. I spoke with Trisha, and she went out of her way to place my order and get it pulled and shipped same day. Thank you Trisha, you are the best.
