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.

I always receive my shipments from Military Fasteners quickly without having to follow up and track down shipments. West Coast shipments arrive usually the next day via UPS ground, making it an effective choice. Thank you for excellent service.

Nice online shop, with very fast operation and high quality service. A bit expensive and without quantity discounts but worth the money in general.
