Customer Reviews

QUICK AND EASY
I was very pleased with the processing of my order from Military Fasteners. Placed my order very late on Thursday. Confirmation was immediate and received a tracking number the next day. It was delivered on the Monday. Excellent service from Military Fasteners
Military Fasteners is an exceptional company in terms of how they run their business. Very prompt and responsive to questions, concerns, quotes, and all other forms of inquiry. Brittany Cornish supports many of the business transactions we perform with Military Fasteners and has made working with them an absolute pleasure. I would highly recommend them to anyone seeking mil-spec hardware.
I have dealt with Military Fasteners a few times and they have always been extremely helpful and knowledgeable. Ramona has always been wonderful to work with and goes out of her way to help you find what you need. Definitely recommended!
