Industry Information


Fasteners are screws, bolts, nuts and all kinds of other tools used to join and secure materials together. There are more than 500,000 types of fasteners available, and they are applied in all kinds of industrial, commercial and consumer products contexts.

Construction fasteners, decking screws, furniture fasteners, self tapping screws, electronic equipment fasteners, appliance fasteners, automotive fasteners and specialty fasteners are just a few fastener varieties. Industrial fasteners are important parts of many industrial products and process equipment. Aerospace fasteners, which are an industrial fastener variety, are any non-threaded or threaded fasteners that are intended for use in aircraft assembly. Titanium is the leading aerospace fastener material, while stainless steel screws and other fasteners are very popular in automotive manufacturing. In the US, fasteners usually follow the American system of measurement, but metric fasteners are more commonly used outside of the US. Fasteners can be threaded, like screws, or unthreaded, like ring or pin fasteners. Fasteners can be manufactured in all shapes and sizes and in a wide variety of materials. While stainless steel fasteners are among the most common varieties, plastic fasteners can also be appropriate in some situations. The wide variety of fastener configurations and compositions open a world of possibilities to professionals throughout industry. This diversity can make choosing the right product a bit of a challenge.

In consideration of applying a given fastener variety, professionals must think of all of the variables that affect the way that fastener will perform in its application. Such variables include the size and shape of the fasteners, the weight of the materials being connected, the fastener's head type and many other considerations. There is a wide variety of head options for industrial fasteners; head type determines how the fasteners will sit against the materials in which they are installed. The type of head also affects the required length of the fasteners. Environmental conditions, such as temperature, moisture and ultraviolet radiation, are also important factors. Chemicals or other corrosive substances to which the fasteners may be exposed and decorative properties required of the fasteners must also be considered. Threaded fasteners, such as nuts, bolts and screws, contain spiral ridges called threads, which aid in the attachment of the threaded fasteners. Continuous-thread studs are used for flange bolting. Two nuts are applied and threaded from end to end. Tap-end studs have a short thread on one end for screwing into a tapped hole and a longer threaded end called a nut-end, which can be either chamfered or rounded. Double-end studs have equal-length threads on both ends with chamfered points and are used for flange bolting or other applications in which torching from both ends is necessary. Other threaded fasteners include sheet metal fasteners, riveting fasteners, and clinching fasteners.

Non-threaded fasteners, such as rivet fasteners, ring fasteners and pin fasteners, do not contain threads. These fasteners can be quickly assembled and removed from components and do not need extra fastening hardware. Bind fastener rivets or pop fastener rivets are inserted into a pre-drilled hole, and a rivet gun pulls on a headed-shaft that passes through the rivet. The shaft breaks or pops, leaving a bulge on the head of the rivet, which holds the two parts together. Dowel pins can be straight, tapered, rolled or grooved and provide perfect alignment, holding parts in absolute relation to one another. Most retaining rings need a groove to seal them into position and are stamped both internally and externally. While some of them may be self-locking, both kinds are used to keep parts from slipping or sliding apart.

Fasteners are generally made either of plastic or metal, depending on their applications. Plastic fasteners are not very strong, so their use is generally restricted to light-duty applications. They can be used to affix upholstery in vehicles and furniture, they can be used to make children's toys and they are used in an extensive variety of consumer products. Metal fasteners are often made of steel, titanium, brass and bronze. Stainless steel fasteners are quite common in the automotive, electric, medical, marine, construction and aerospace industries because of their strength and resistance to corrosion and heat. Depending on the material, fasteners are manufactured and produced a number of different ways. Most plastic fasteners are injection molded. Metal fasteners are made by heating and casting. Threaded fasteners go through a process called thread rolling, in which a die made of harder metal than what the fastener is made of, with a threaded profile, is pressed onto a rotating work piece. The force is increased, and the thread profile is transferred onto the fastener via cold working. Carefully pairing a fastener with its application is essential to ensuring the effectiveness and longevity of the fastener and the materials in which it is installed.

Points to Remember While Choosing the Fastener for Your Products

Fasteners are a primary necessity for many manufacturers. These simple components hold things together and help join parts to make a complete device, machine or tool. Obviously, if the quality of the fasteners is substandard, they can loosen or break, which will ultimately result in the device or machine failing. In other words, fasteners can more or less dictate whether your products will be a success or a failure. This is the reason manufacturers need to pay a lot of attention to the selection of fasteners, and many of them invest a lot of money and effort in specialty fasteners.

Choosing the right fastener for your product is a tough challenge. However, being aware of certain points will make the job much easier, allowing you to make prudent decisions. Below, we try to present some scenarios that will help you to decide the right type of fastener, whether your requirement is automotive fasteners, self-tapping screws, or aerospace fasteners.

Think about the primary use of the product: This should be primary in considering while choosing the fastener type-the end use of the product that the fastener is intended to be used for. If the product has enclosures that need to be opened and closed frequently, or if it is used in parts that moves or vibrates, metal fasteners should be an ideal choice. When the product is such that it will be never opened in its lifetime, inexpensive alternatives such as plastic fasteners will do just fine.

Know your requirement: Before choosing the fastener for your design, another important aspect to consider is to understand your specific needs. Your product design will dictate the primary function, size and material of the fastener. Failing to consider this can lead to the fastener not doing the job properly, ultimately affecting the performance of your product. In addition, you need to pay attention to the threads of the fastener. If your design calls for a multiple thread fastener, a single threaded one will not do. Never use metal that is too heavy for your application, and never ask your provider to meet critical tolerances that your product does not need. The same goes for the size of the fastener as well.

Finish and function: Settle on a finish for your fastener after your provider studies your requirement. You need to choose the finish hardness according to your product design; make sure that the metal grade and gauge thickness is the same as your application. Moreover, when ordering, communicate to your supplier what job the fastener is supposed to perform, and ask about fastener limitations.

Price: Cost is always a concern for everything we do. This is especially true to manufacturers, since the primary motive of a business is to earn profit. Since fasteners are a basic need in lot of industries, businesses generally look to cut corners to save cost. Avoid this. Cutting cost on fasteners may help you gain few dollars in the short-term, but in the end, it can have a devastating impact on your reputation, as low quality fasteners may fail which will ultimately lead to failure of your product, dealing a blow to your brand.

Fasteners: A Brief Look at Their History

Fasteners are everywhere and they are used in almost every piece of equipment we use in our day-to-day life. In fact, they are so commonplace that we barely notice them, let alone truly understand their importance and place in the history of human civilization.

The history of fasteners dates back thousands of years. A simple but groundbreaking invention that started hundred years before the common era, fasteners are now an important element of almost all equipment, machines, and devices-from automotive fasteners to aerospace fasteners, self-tapping screws to nuts and bolts.

Many believe that Greek philosopher Archytas of Tarentum, sometimes credited as the father of mechanics, invented screw threads around 400 BCE. The screw principle was first applied in presses to extract oils from olives and juice from grapes. Oil presses found in Pompeii worked by the screw principle. Archimedes, the great Greek mathematician developed the screw principle and utilized it to make devices to raise water. The water screw was made from wood, it was used for farm irrigation and to get rid of bilge water from ships. The screw got its first mention in Mechanica of Heron of Alexandria in the first century AD.

Screws took a great leap in the Eighteenth Century when Antoine Thiout equipped a lathe with a screw drive in about 1750; this innovation allowed the tool carriage to be moved longitudinally semi-automatically.

Meanwhile, there is no clear consensus among experts as to when nuts and bolts, probably the most common type of fasteners, came to be originated. No doubt, its roots were planted when the screw thread was invented. The most prominent advancements in current-day bolt and screw processes were achieved during the last 150 years. Nuts and bolts were firmly established as an important component of engineering and construction during the Industrial Revolution. According to W.R. Wilbur, Besson in France created the first machine for manufacturing bolts and screws in 1568. Besson later made a screw-cutting gauge or plate to be used on lathes. The device came to be used widely after the English company, Hindley of York, perfected it in 1641.

The U.S. Standard Thread was formed in the early 1870s. Then came the Society of Automotive Engineers (SAE) standard, and screw thread designs continued to evolve. Self-drilling screws started to make their mark by late 1960s in the metal building industry. It was introduced as a "pinched point" (or cold forged) self-drill and there was some apparent benefits of using the self-drilling fastener, including the decrease in the overall time and cost of installing the fastener.

There has been tremendous development in fastener designs in the past twenty years, as industries started using nickel-based alloys. This material can withstand high temperature environments like turbochargers and engines where steel does not perform well. There is ongoing research and development of lightweight metal bolts from metals like aluminum, magnesium and titanium.

Modern-day fasteners have come a long way from their Greek lineage, sparking industrial development and human progression.

Fastener Types

  • Aerospace fasteners are screws and bolts used in the assembly of aircraft.
  • Automotive fasteners are connecting tools used in the manufacture of automobiles.
  • Decking screws are fasteners used primarily in the construction of wooden structures like outdoor decks.
  • Breakstems are fasteners that are installed by pulling the end of the mandrel or stem, resulting in the breakage of the stem at the breaker groove and leaving the head of the stem within the fastener body.
  • Case hardened fasteners have received heat treatments resulting in a fastener surface that is harder than the core.
  • Industrial fasteners are screws, bolts, nuts and other connecting tools used in or produced by industrial processes.
  • Metric fasteners follow the metric system instead of the American Customary system. Conversion charts are available from most fastener manufacturers.
  • Mil spec fasteners comply with U.S. federal and military specifications for fastening mechanisms.
  • Nuts and bolts work together to form a common fastening mechanism. A bolt is an external threaded fastener that consists of a partially threaded shaft, which penetrates the object connected and is held in place by nuts; nuts are metal blocks with complementary internal threads that grasp the upper shaft of the bolt and secure the work piece together.
  • Panel fasteners function as latching mechanisms on doors and compartments and join panels on cabinets, workstations and appliances.
  • Plastic fasteners are screws, nuts, bolts and other fasteners made of plastic materials. While plastic fasteners are not as strong as metal fasteners, they are still popular in applications like upholstering, consumer products manufacturing and many other examples.
  • Rivets and pins are non-threaded fasteners commonly used on door hinges and pulleys, as well as furniture and electronic equipment. Pins are placed into aligned holes in the joined parts, forming a secure connection.
  • Screws are externally threaded fasteners consisting of a spiral-shaped shaft and a head. The shaft fits into a work piece and is held in place by the head.
  • Self tapping screws are threaded fasteners that can be screwed into surfaces that have not been tapped.
  • Specialty fasteners are available through many fastener manufacturers. Specialty fasteners can be custom-made according to specific customer requirements.
  • Stainless steel fasteners are strong, corrosion and heat resistant mechanisms that are useful in countless applications in the automotive, electronic, medical, marine and construction industries.
  • Stainless steel screws are threaded fasteners made of stainless steel; these products are attractive because of their strength and corrosion resistance. 
  • Threaded fasteners are screws, bolts and other connecting tools that are machined or rolled with ridges called threads.
  • Through-hardened fasteners have received heat treatments, resulting in consistent hardness throughout the entire fastener.
