Science 6 Screw

A screw is a simple machine that consists of a threaded shaft with a head. It converts rotational motion into linear motion by using its threads to move into a material when turned. The threads provide traction while the head can be turned by a tool. Common types include wood screws, machine screws, and sheet metal screws. Screws are widely used in construction, furniture assembly, household appliances, automobiles, electronics, toys, sports equipment, and more to hold objects together or lift objects.
