A fastening mechanism is a device or system used to securely hold two or more objects together. Common examples include screws, bolts, and clips, which provide stability and strength in various applications. Fastening mechanisms are essential in construction, manufacturing, and everyday items, ensuring that components remain in place during use. These mechanisms can be categorized into permanent and temporary types. Permanent fasteners, like welds, create a lasting bond, while temporary fasteners, such as nuts and washers, allow for disassembly and reassembly. Understanding different fastening mechanisms is crucial for selecting the right one for specific tasks or projects.
