Threaded fasteners, such as SCREWS, are a type of mechanical fastener used to join two or more objects together. They are typically made from metal and feature a helical ridge, known as a thread, which is used to create a tight and secure connection when the fastener is inserted into a pre-drilled hole and rotated. SCREWS are one of the most common types of threaded fasteners and are used in a wide variety of applications, from furniture assembly to automotive repair.
