Screw thread Wikipedia

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
