Although known as a vise manufacturer, G. M. Yost Manufacturing Co., also called G. M. Yost Co., was an established manufacturer of nut-facing machines in Waynesboro, PA in 1906. Gilmore M. Yost had previously been manager of vise manufacturer Emmert Manufacturing Co. The firm's change of product lines began in early 1907 with the purchase of what was called the Snediker vise plant in Yonkers, NY, from Peter A. Frasse & Co. The factory had manufactured for Snediker and Stephens Patent Vise Co., and Frasse had taken it over in late 1906. Yost moved the plant's machinery to Mechanicsburg, PA, to begin operations there. Yost apparently also bought rights to the Snediker and Stephens vise patents. The firm built a new plant in Meadville in 1908. In 1910, Yost bought Williamson Vise Co., a 7-year old firm in Bradford, PA. Yost initially produced machinists' bench vises and leg vises, but by 1910 were making the Yost Universal woodworkers' vise. Their brand names in 1913 included Stephens and Williamson. By 1916, Yost had begun an association with a competitor, Columbian Hardware Co. By 1930, the company name was Yost Manufacturing Co.

In 1950 they company relocated to Muskegon, Michigan. They stayed there until 1980 when the moved to Holland, Michigan. In 20201 they were acquired by Eastwood Automotive.
