Customer Reviews

Order was shipped extremely fast. I dont know how you get these orders shipped as fast as you do. Everything was perfect. Thanks
As a race car owner and builder I find your pricing and selection of AN hardware and composite materials more than meet my needs and expectations.
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.
Thanks Military Fasteners, you folks continue to be the best in filling orders and getting them out quickly. You are my go to source for all things aviation.
