Contract Manufacturing Services at OSP

Ohio Screw Products, Inc. (OSP) is more than a machining company — we are a contract manufacturing partner dedicated to producing precision parts that meet the highest standards of quality, performance, and reliability. With over 75 years of experience, a fully employee-owned culture, and certifications including ISO and ITAR, OSP delivers the expertise and commitment you need to bring your products from concept to completion.

Our capabilities include CNC machining, multi-spindle machining, milling, and traditional screw-machine operations. This blend of modern technology and proven processes allows us to manufacture parts with tight tolerances, repeatable accuracy, and consistent quality.

What is Contract Manufacturing?

Contract manufacturing allows companies to outsource the production of parts or components to a specialized manufacturer with the equipment, skills, and certifications required to achieve reliable results. This partnership reduces costs, shortens lead times, and ensures products meet exact specifications.

At OSP, we provide end-to-end contract manufacturing and CNC machining solutions, combining advanced technology with strict material testing and quality control. Our approach ensures that every part we produce — whether for aerospace, defense, medical, automotive, or industrial markets — performs exactly as intended.
