A fastener is a hardware device used to join or affix two or more objects together, typically in the context of construction, manufacturing, and assembly processes. Fasteners serve as essential components in various industries, providing secure and reliable connections that can be disassembled or permanent, depending on the application.

Common types of fasteners include screws, bolts, nuts, washers, nails, and rivets. Screws and bolts are threaded fasteners designed to be inserted into pre-tapped holes or to work with nuts, creating strong, adjustable connections. Nails are usually hammered into materials like wood for quick fastening, while rivets are permanent fasteners often used in metalwork. Washers are used to distribute load and prevent damage to surfaces.

Fasteners are made from a variety of materials, including steel, stainless steel, aluminum, brass, and plastics. Material choice depends on factors such as strength, corrosion resistance, weight, and environmental conditions. The design and size of fasteners are standardized in many industries to ensure compatibility and safety.

Fasteners are crucial in ensuring structural integrity, safety, and durability across numerous applications, from household furniture assembly to aerospace engineering. Proper selection and installation of fasteners are vital for the performance and longevity of assembled structures.

The development and use of fasteners date back thousands of years, with early examples including simple nails and wooden pegs. Today, advancements in manufacturing technology have allowed for highly precise and specialized fasteners to meet diverse technical requirements worldwide.
