Fasteners

Fasteners are essential components used to mechanically join or affix two or more objects together. They are widely used in construction, manufacturing, automotive, aerospace, and a variety of other industries. Fasteners come in many types, each designed for specific applications depending on factors such as load requirements, material types, and environmental conditions.

Fasteners come in an extensive array of shapes, sizes, lengths, and types, from common nails to large bolts designed to secure heavy-duty manufacturing equipment. They can be either generic or specially designed for specific applications. Each industry and manufacturer has unique requirements for these versatile tools. The variability among fasteners is a result of the extreme forces they must endure. Fasteners are designed to hold parts, components, and machinery together under significant vibrations and pressure, while still allowing for disassembly when needed.

Fasteners can be categorized in several ways, including permanent versus non-permanent and threaded versus non-threaded. Permanent fasteners, such as rivets and couplings, are not meant to be removed. Threaded fasteners include screws and bolts, while non-threaded and permanent fasteners include dowel pins and blind fasteners.
