Precision and Quality Begin with the Right Material — OSP Delivers Both

Ohio Screw Products, Inc. (OSP) combines advanced machining technology with strict material testing to deliver precision parts from both ferrous and non-ferrous metals. As a contract manufacturer, our focus is on accuracy, repeatability, and reliability. Whether you require carbon steels, stainless steels, aluminum, copper, engineered plastics, or specialty alloys, OSP provides parts that meet your specifications with quality and consistency.

OSP Material Testing & Quality Selection Process

At OSP, precision doesn’t start at the machine — it begins with the selection and testing of raw materials. Every component we manufacture undergoes a rigorous quality process to ensure that the material performs exactly as expected in your application.

Our process is built on industry-leading standards and decades of expertise. This ensures that whether you are sourcing parts for aerospace, automotive, medical, or industrial machinery, OSP delivers components that are built to last.

How OSP Ensures Material Quality

Certified sourcing – We only work with trusted, approved mills and suppliers that provide full certification and traceability. This ensures materials meet recognized standards before they even arrive at our facility.

Chemical analysis – Advanced testing verifies alloy composition, eliminating impurities and ensuring material integrity. This step guarantees the consistency needed for high-performance applications.

Mechanical testing – Strength, hardness, and ductility are measured to confirm that metals and plastics perform reliably under load.

Corrosion testing – Stainless steel, aluminum, and other corrosion-resistant materials are tested for durability in harsh conditions.

Traceability – Every batch of material is fully documented, giving customers confidence in origin, certification, and performance.

By combining material science and machining expertise, OSP ensures that every customer receives precision parts built on a foundation of strength, reliability, and certified quality.
