Areas where Rivets are used as a Helping Tool
A cost-effective fastening alternative for many assembly applications, rivets, are common for a locomotive industry as well as on plant floors. They are ideal for flexible joints or tightly joined mating components. As they are inexpensive, they are specially required for pivot joints or mechanical repetitiveness.
Locomotive Industry
A key step in steam locomotive assembly is the boiler-making, which was very slow and a laborious process. Therefore, by using a rivet thrower that would grab a glowing-hot rivet from a furnace and flip it to a holder that can crouch inside the boiler that was being assembled. Assemblers generally prefer to use studs or bosses, as a result, new processes and tools, such as orbital riveting, radial riveting, blind rivets and self-piercing rivets, have become more popular in recent times. There are other tools and techniques, such as threaded fasteners, welding and adhesive bonding which are commonly used in all the industries to create joints.
The Inexpensive Fastener
Out of all types of rivets, loose rivets offer numerous benefits to assemblers, such as simplicity, dependability and relatively low cost. They are mainly the fasteners of choice for assembling products such as brake shoes, medical instruments, seatbelt retractors, scissors, pliers, airbag assemblies, door hinges, toggle clamps, pulleys, caster wheel assemblies, furniture mechanisms, staplers, chainsaws and garden tools.
Benefits for Daily Use
They are popular because of the multifaceted applications they offer. They allow high production rates, they can be used on assemblies of varying complexities, also easy to inspect and requires no maintenance. Additional benefits would include fastener strength, product strength after riveting and a clean fastening process. Also, a good choice for a product to be tamper-proof for safety and liability reasons.
Points to Remember
In the compression method of riveting, the head of the rivet is formed by pulling or squeezing the rivet shank. The head is formed by the force of the impact against the top of the shank in the impact method. In nonimpact riveting, the head is formed by a rolling or spinning action against the top of the shank.
These fasteners are generally used for lap joints, where the clearance hole into which they are inserted must be close to the diameter of the rivet. Unlike any other fasteners, these swell up in the hole and provide extra support.
The forged grain structure of rivets has a higher compression and shear strengths than many other mechanical fasteners. But, they are not recommended for transmitting loads in tension. Their tensile and fatigue strengths are lower than those of bolts. It may result in permanent failure when loads exert movements that cause a prying action on the head.

Use of Riveting Machines
The setting equipment ranges from small handheld rivet guns to large machines. Selection criteria depend on the types being used and the types of material being joined.
Rivet guns like handheld, hydraulic or pneumatic are typically used for applications that require versatility, such as assembling products in tight or confined spaces. Pliers-like manual setters are available for low-volume or custom applications, such as bookbinding.
Large machines also include single and double-spindle automatic riveters, multiple machine systems and automated riveting systems. The single-spindle automatic machines are the simplest and the most popular ones. They are very flexible and can be mechanical, hydraulically or pneumatically operated. Machines equipped with monitors and sensors can track vital information because of the amount of force put on these fasteners.
