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.

Military Fasteners never fails to have exactly what I am looking for and at a great price as well. Their quick turnaround allows me to have what I order in hand before my deadlines. Would definitely recommend them every time.
