Customer Reviews

Brittany was attentive to our needs. We had to source some other products you didn't have elsewhere. We would have preferred to place an order a one place. Will come back and order another time.
We worked with Ramona at Military Fasteners for a few items that we needed right away to complete a job. Ramona processed our order quickly and efficiently and made the experience stress free when it could have been quite challenging. The items came with all the correct documentation too which was also very important to us.
When I need materials for a project Military Fasteners provides the selection, prices and great shipping speed and rates that I need.
My orders have been delivered on time or earlier all packaged well and in good shape. Thank you Military Fasteners.
