Fasteners are hardware devices used to join or secure two or more objects together. Common types of fasteners include screws, bolts, nuts, and nails. They come in various materials, such as metal, plastic, and wood, and are designed for different applications, from construction to automotive assembly. Fasteners play a crucial role in ensuring the stability and integrity of structures and products. In addition to traditional fasteners, there are also specialized types like anchors and rivets. Anchors are used to secure objects to walls or ceilings, while rivets are permanent fasteners that hold materials together by deforming the end of the fastener. Understanding the right type of fastener for a specific task is essential for effective assembly and safety.
