ABOUT US

U.S. Tool and Manufacturing Company has a long standing commitment to quality and service.  It started back in 1921 when the company manufactured many different types of products ranging from stop light switches to battery trays.  However, as the years progressed, the company focused its strength toward the manufacturing of expansion plugs, better known as core plugs. 

 

Today, U.S. Tool and Manufacturing Company is a full line basic manufacturer of all core plugs for the automotive aftermarket.  As we move ahead and adapt to the changes in business, we continue to place a strong emphasis on providing the best quality   

product in the industry.
