I enjoy ordering my components from military fasteners because your people that take my order have always got my order right. They are also very polite and professional. Thank You

I placed an order with Lindsey at Military Fasteners late afternoon, 3:15 to be exact and she was nice enough to expedite my order and made sure to get it shipped that day. Great company with great people.

5.0

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.
