Screw Threads

Screw threads are an essential component in a wide range of mechanical systems. They are used to fasten two or more objects together, transmit rotational motion and power, and help convert rotary motion into linear motion. Threads are formed by cutting or rolling a helical ridge onto the surface of a cylinder or screw.
