NOTE: Screw Thread – A screw thread may be visualized as a flexible form, like a piece of string that has been wrapped around a cylinder, or the sides of the cylindrical hole, at a uniform rate of advance, producing a form known as a helix. It may also be considered as a raised form produced on the outside of a cylinder, or on the inside walls of a cylindrical hole after a thread-cutting operation has been completed.arrow_forward
