About Us


Southern Gage was founded in 1955 in Erin, TN as an outgrowth of the Woodward Company. 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. 


Moving Forward...

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.
In 2017 GSG CT announced it would add 25,000 s.f. onto its operations to keep up with the growing needs of our customers.
Investing in new state of the art equipment and relocating some of its current resources, GSG is to begin moving into the new area in April 2019. 
In 2019, GSG TN invested substantially in CNC thread grinding equipment to improve lead times.  
Both facilities have hired many new gage makers and apprentices in an effort to ensure our "tribal knowledge" gets passed onto the next generation. Glastonbury Southern Gage is focused on remaining the "World Class Gage Company" it has grown the reputation of being for almost 65 years.
