What is fastener?

A fastener is a hardware device that mechanically joins or affixes two or more objects together. Fasteners can be used to securely hold objects in place, or to allow for easy disassembly and reassembly of components. Common types of fasteners include screws, bolts, nuts, rivets, and nails. Fasteners are used in a wide range of applications, from construction and manufacturing to automotive and aerospace industries.

A fastener is a mechanical component used to hold two or more objects together in a secure manner. It is designed to be inserted, secured, or removed by mechanical means, and can be used in a wide variety of applications. Common types of fasteners include bolts, screws, nuts, washers, rivets, pins, and nails.

Fasteners are typically made of metal, plastic, or ceramic, and are chosen based on the strength, durability, and corrosion resistance required for the specific application. They can also be coated or treated to improve their performance and extend their lifespan.

The selection of the correct fastener for a particular application depends on factors such as the type of materials being joined, the load requirements, the operating environment, and the accessibility for installation and removal.
