State two uses of screw?

1. To fasten objects together by turning the screw into a threaded hole or nut.
2. To apply pressure or force by turning the screw, such as in a clamp or vise.

- To hold objects together: Screws can be used to hold two or more objects together by creating a secure connection. This is a common use for screws in construction, furniture assembly, and other applications.
- To move objects: Screws can also be used to move objects, such as lifting a heavy object or adjusting the height of a table. This is done by using a screw to create a mechanical advantage, which allows for a greater force to be applied to the object.
