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.

As normal with Military Fasteners for many years, no issues. I order the parts needed and they send them. Just fair prices and good service.
