I recently requested a quote and placed an order with Kristen Belmont. Kristen was incredibly helpful, prompt, and informative, addressing all of my inquiries and requests efficiently. I am extremely grateful to have had Kristen's assistance.

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.

Trisha Hawkins and her team at Military Fasteners are absolutely incredible. We do a lot of Government and Military work and due to this there are a ton of restrictions with what products we can use. I called Military Fasteners (MF) with an extremely HOT request. Trisha was able to source those part numbers, tell me they were in stock and ready to ship. I ordered these on a Wednesday at 4:00pm. They shipped the same exact Wednesday, we received that weeks Friday, even though we were guaranteed Monday/Tuesday. Trisha - THANK YOU! Trisha's Team - THANK YOU! I will only be ordering my military hardware from you all.
