Year in and year out - your staff is excellent, attentive, and spectacular. My last order I forgot an item, and called in to have it added. Sure enough there it is in the box, just as requested. Customer service is always fantastic. Keep up the good work!

I ordered 2 custom coax cable assemblies in the early afternoon, and was shocked when I was notified they shipped later that day! Great service!

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.
