Standard screws are fasteners used to hold objects together. They typically have a cylindrical shaft with a helical ridge, known as a thread, that allows them to be driven into materials like wood or metal. Standard screws come in various sizes and types, including wood screws, machine screws, and self-tapping screws, each designed for specific applications. These screws are made from different materials, such as steel, stainless steel, or plastic, to suit various environments and requirements. The head of a standard screw can be shaped differently, including flat, Phillips, or hex, allowing for different tools to be used for installation and removal.
