Southington Tool & Mfg. Corp was founded on July 7, 1970 by Edward W. Kalat. From its beginning as a supplier to the hardware industry, STMC quickly expanded. In 1978, STMC began providing quality components to the medical industry. Since then, STMC has expanded into the aerospace, electrical, automotive, firearms, and other markets.
