Fasteners
A fastener is a mechanical device designed to connect two surfaces or objects, either in a permanent or temporary way. Non-permanent fasteners allow for easy separation of the joined materials without causing any harm. On the other hand, removing permanent fasteners generally requires considerable force and can potentially damage the surfaces they bind. These permanent fasteners are intended to offer a durable and reliable attachment.
The Importance Of Fasteners
Fasteners are a vital component of the construction industry, serving as the connective tissue that holds structures together. They provide structural integrity, help to distribute loads and stresses of the building and keep the structure stable and secure.
Safety
Fasteners are critical to ensuring the safety of structures. Properly selected and installed fasteners ensure that materials are securely fastened together and that structures can withstand the loads and forces placed upon them.
Durability
Fasteners play a key role in ensuring the durability of structures. They must be able to withstand environmental factors like moisture, heat, and corrosion and must be made from materials that can withstand the rigours of the construction process.
Stability
Fasteners help maintain the stability of structures. They can be used to reinforce and strengthen connections between materials and structures, providing additional support and ensuring that the structure remains stable over time.
Versatility
Fasteners come in a wide variety of shapes, sizes, and types, making them highly versatile. They can be used for a wide range of construction projects, from small home renovations to large-scale commercial developments.
Threaded fasteners are easy to install and uninstall. Three types of threaded fasteners are:
Bolts
This type of threaded fastener has a hex head on one end and is threaded on the other end. Bolts are often used with a nut or washer to keep them in place. The bolt is inserted through the two parts you are trying to join before being secured in place by the washer. Here are some of the types of bolts available:
●Carriage bolts: These bolts have domed heads. The component under the head is square to keep the bolt from moving while you are tightening the washer.
●Plow bolts: If you are working with heavy-duty equipment, plow bolts are a great option. They have non-protruding heads, which makes them perfect for various demanding applications.
●Flange bolts: This style helps distribute loads evenly because of their circular flange beneath the head. You will also see them referred to as frame bolts.
Screws
Screws are likely what comes to mind when you think of a fastener. Like bolts, screws also have a hex head on one end and are threaded on the other end. They are different from bolts, as they are screwed into an internally threaded hole for added security. They are one of the most versatile fasteners since they do not require anything extra to hold them into place. The most common types of screws include:
●Wood screws: These screws have a tapered head and coarse threads.
●Drywall screws: Drywall screws have a self-starting head, which allows them to countersink without causing any damage.
●Masonry screws: Masonry screws have a hex head design and a flat tip.
●Deck screws: Similar to wood screws, deck screws feature corrosion resistance and a self-tapping design that makes them suitable for outdoor use.
Studs
Studs have no head and are threaded on both ends. They are used to join two other objects with internally threaded holes. Studs are usually meant to provide a permanent attachment and are often welded or bonded. Here are some common types of studs:
●Fully threaded stud bolts: These stud bolts are the length of a threaded bar and, combined with nuts, are often used for fastening large pieces together.
●Double-end stud bolts: Both ends of this stud bolt are threaded to equal lengths with a shank in the middle.
●Tap end stud bolts: This stud bolt has a shank and longer thread on one end and a short thread on the other to be screwed into the prepared hole.
●Clinch stud: These studs have tapered heads with teeth so they can be permanently secured to sheet metal.
How Are Fasteners Made?
Fasteners undergo various manufacturing methods depending on the type of fastener and the material they are made with. Here are some of the most common manufacturing methods:
Cold forging
Cold forging creates a fastener that has better physical and mechanical properties than other methods.
Hot forging
This method is better for fasteners with larger diameters, as the metal is made more malleable. Fasteners with more complex shapes are also easier to manufacture using this method.
Machining
Using this method, the material is cut into a shape rather than molded. This is best for non-standard fasteners and smaller amounts of them, as it is time-consuming.
