Customer Reviews

Great supplier to work with. Prompt replies to inquiries, accurate information, quick turnaround shipping, personal touch with all communications. Trisha Hawkins has been a great representative for all of our questions and concerns.
Ive been dealing with you for many years and as usual the service and excellent quality is consistently above average. Its a pleasure to do business with Military Fasteners.
Tanks for the fantastic service. I ordered over the new year period and was amazed my shipment arrived so fast, all the way to New Zealand. Less than a week and that included clearing Customs. Awesome!!
I sent in my online order then within a minute I realized I left off an item. I sent a message that requested an item be added to avoid a second shipping cost. I received a reply the next morning that the item I wanted had been added successfully and my order would be delivered as promised. Thanks to your staff for the flexibility and the help with my online order.
