A screw, often referred to as a twist, is a simple yet effective fastener used to hold objects together. It has a helical ridge, known as a thread, that allows it to be twisted into materials like wood or metal. When you turn a screw, the threads grip the material, creating a strong bond. This makes screws essential in construction, furniture assembly, and many everyday items. The design of a screw allows for easy installation and removal, making it a favorite among DIY enthusiasts. Different types of screws, such as wood screws and machine screws, serve various purposes, ensuring that there’s a suitable option for almost any project.
