OSG's Blog for

As a leading manufacturer of cutting tools, OSG Tap & Die is best known for our high performance, quality taps. But there is less attention brought to our other namesake: the OSG Die Division. Ten years after OSG Corporation was founded in 1938 in Tokyo, Japan, Sterling Die Operation was established halfway across the globe in Cleveland, Ohio. These two companies continued to grow separately, towards a future where the two would eventually merge to become one internationally successful business.

Sterling Die Operation began as a supplier of thread rolling dies. During its early years, the company focused on manufacturing for the Aerospace and Defense industries in the late 60’s and early 70’s, and as technology progressed, worked its way into the Automotive and Industrial industries in the 1990’s.

At the turn of the century, Sterling Die Operation achieved international recognition by becoming ISO certified. To date, they have never failed an ISO audit. This accomplishment has allowed the company to expand to global markets, which ultimately made the eventual merger with OSG possible.

On June 1st, 2004, OSG Tap and Die purchased Sterling Die Operation from its previous owner, EnPro Industries, Inc. Four years later, under the name Sterling Die, Inc., OSG Fastener Products Division merged with Sterling to create a stronger overall company.

This Parma, Ohio branch of OSG is now one of the largest full-line domestic die manufacturers in the United States. This modern facility now offers a wide range of products for the thread forming industry including flat, cylindrical, planetary, trimming, rack and segmented carbide dies, along with bent shank taps, nib taps and gages. They also provide reconditioning services for OSG and non-OSG dies. By combining OSG’s global history with Sterling Die’s hardworking perseverance, we have molded a company with a well-rounded future to shape the dreams of our customers worldwide.
