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.

I am unable to add any suggestions. Military Fasteners is an on time provider. I have never understood why the orders from you company are shipped and arrive in time given to me. Other companies say same day ship or the following day and it takes much much longer for the product to arrive. All I say, Good Job

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!
