It grew to be a full service gage manufacturer with emphasis on thread gaging. During the 1980's Southern Gage became known for its educational and training programs on thread form and gaging. In 1995, the owner of Glastonbury Gage purchased Southern Gage from ITW. In March 1999, the GSG Erin operations occupied its new 42,000 square foot state of the art manufacturing facility. It includes 5,000 square feet of laboratory space, temperature and humidity control for the entire plant, CNC thread grinding equipment and a streamlined process work flow. In July 2001 GSG consolidated customer service and plain cylindrical production to improve deliveries and customer response, while this effort was successful we at GSG continue to find ways of improving delivery and customer service. We intend to build on this platform to offer our customers quality products and services at competitive prices.
