Welcome to our introduction to fasteners. A fastener is a hardware device that mechanically joins or affixes two or more objects together. These essential components serve the primary function of creating secure connections between separate parts, enabling both assembly and disassembly when needed.
Fasteners can be categorized into two main types. Threaded fasteners include screws which have self-tapping threads, bolts which require nuts for assembly, and studs which are threaded rods. Non-threaded fasteners include nails that are driven into materials, pins which are cylindrical fasteners, and rivets that create permanent connections between parts.
Fasteners work through different mechanisms depending on their type. Threaded fasteners create clamping force through thread engagement, converting rotational motion into linear force that holds materials together. Friction-based fasteners rely on friction and interference fits, creating tight connections between materials. Examples include nails, pins, and press-fit components that use mechanical interference to stay in place.
Fasteners have widespread applications across many industries. In construction and building, they provide structural connections for framing, foundations, roofing and siding. The automotive industry relies on fasteners for engine assembly, body panels, and interior components. In electronics and appliances, fasteners are essential for circuit board mounting, case assembly, and component attachment, ensuring reliable connections in complex devices.
To summarize what we have learned about fasteners: They are essential hardware devices that mechanically join objects together. Fasteners fall into two main categories of threaded and non-threaded types, working through either clamping force or friction-based mechanisms. These components are vital in construction, automotive, and electronics industries, enabling both permanent and removable connections as needed.
