About Us

The UK’s number one manufacturer of thread and plain gauges

Established in 1977 by the late George Ratcliffe, Threadmaster remains an independent family business, now run by George’s son John Ratcliffe. In keeping with George’s vision, Threadmaster, although still using traditional thread grinding equipment, continues to invest in modern CNC machinery to ensure it remains one of the leading gauge manufacturers.
