A screw thread, often shortened to thread, is a helical structure used to convert between rotational and linear movement or force. A screw thread is a ridge wrapped around a cylinder or cone in the form of a helix, with the former being called a straight thread and the latter called a tapered thread. A screw thread is the essential feature of the screw as a simple machine and also as a fastener.
Thread grinding is a form of threading during which a CNC machine with an abrasive grinding wheel is used to cut the threads of the screw. Screws created through thread grinding are able to meet custom backlash requirements and tight tolerances.
