Mar-Bro Manufacturing was founded in 1983 by Fred and Helen Martinez. What began as a small, family business has since become a stronghold of the fastener industry.

While our company continues to grow, our values remain the same. We do what is right and we do what is fair. We have a track record of quality, integrity, dependability and success. It’s a way of doing business that has helped us secure long-term relationships with customers from around the globe. Mar-Bro’s fasteners can be found in a wide range of industries including aerospace, automotive, oil and gas drilling, nuclear, semiconductor and military.

Among our strengths is versatility. Mar-Bro’s production processes include both cold and warm forging. Our equipment blends classic methods of fastener manufacturing with some of the most state-of-the-art technology available. We manufacture standards, specials, MS and NAS fasteners. Our facility includes a tool and die shop to ensure quick turn-arounds when rush orders are required, and we maintain an in-house testing laboratory which is A2LA accredited in accordance with ISO/IEC 17025.

We also take great pride in the fact that our fasteners are American made. Everything Mar-Bro manufactures is forged on-site at our headquarters in Phoenix, Arizona.

It’s about doing what you like and liking what you do. At Mar-Bro, we are fortunate to be achieving both. We owe our success to our customers and appreciate the opportunity to share that success with you.
