The Craft Is In Our DNA

At R&S, the people on the floor are the product. We're a team of genuine machinists — hands-on, detail-obsessed, and fully committed to the customers who trust us with their most critical components.

St. Louis Roots. World-Class Standards.

R&S Machining has been a fixture in St. Louis manufacturing for decades, earning its reputation one tight-tolerance part at a time. What started as a skilled shop serving regional industrial customers grew into a trusted precision machining partner for some of the most demanding OEMs in aerospace, defense, and medical. We've always believed that staying focused — on quality, on our customers, on the craft — is what separates good shops from great ones.

Today, R&S is proud to be part of Threadlock Precision, a network of leading American precision manufacturing companies in aerospace and defense. Through shared resources, capital investment, and a common commitment to excellence, Threadlock makes us stronger — without changing what made us good in the first place.

Dedicated and mission ready!

Longevity matters in this business — and our team shows it. Most of our people have been with R&S for five or more years, with a core group bringing over two decades of hands-on experience to the floor every day. These aren't operators pushing buttons — they're machinists who take ownership of every part they touch. We invest in training and continuous improvement because we know that standing still in precision manufacturing means falling behind. We grow together, and we deliver together.
