BT Crellin specializes in both ID and OD single point threading for diameters ranging from 1/8" to 8" or greater, depending upon part configuration. Almost all first operation threading machines (Brown & Sharpe and Acme's) are equipped with threading attachments. An extensive selection of die heads and tapping fixtures are available to meet any threading machine requirement. We are capable of producing both standard and special threads, including but not limited to Acme, metric, and British Standard style threads.
