[0002] Screws are commonly found in machinery, electrical appliances, and buildings. They are generally made of metal or plastic, cylindrical in shape, and have concave and convex grooves on the surface called threads. The main function of a screw is to join two objects together, or to fix the position of an object. Screws can usually be removed or re-tightened at will without losing their efficiency. Generally, the top diameter of a screw is larger, and common shapes are round, square, or regular hexagonal. If the top is a regular hexagon, the screw can be turned with a wrench. If the top is round, there will also be grooves on the front of the top, which is convenient for using the corresponding screwdriver to turn the screw. The most common grooves are flat, cross, and square, and there are other shapes.
