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.
