What is a rivet?
Rivet is one type of mechanical fastener that creates a permanent joint with more two or more items. It has been widely used in many applications and different industries. Rivet is composed of a head on one end and a cylindrical stem (usually we call it tail) on another end and usually made out of low carbon steel. It has a flat unthreaded shaft that inserted through a hole created for joining two or more items together. The shaft can prevent radial movement of the items. Rivet is durable, strong, good at supporting the shear load, resisting considerable forces and vibration. A rivet can also be made of other materials such as aluminum or copper if the weight and level of corrosion resistance are important to the applications. The rivet can be used to join about any type of material, a small rivet can join paper and wood pieces, while a large rivet can join metal or other heavy-duty items. They are many types of rivets with different purposes, materials, shapes, sizes, and applications in Malaysia. The types of rivets include the standard round head, blind, semi-tubular, drive, flush, countersunk, friction-lock, Oscar, and self-pierce. We will introduce them further in this article.
What is a solid rivet?
Solid rivet is one of the oldest, most reliable, and commonly used types of fastener which has been using since the Bronze Age . Solid rivet is also known as a round rivet. It has a very traditional design which consists of a smooth cylindrical shaft and a head on one end. The solid rivet can have different designs on the head such as countersunk head rivet, protruding head rives which including round head rivet, flat head, universal head, and brazier-head. When installing the rivet, we need to use it together with a hammer, crimping tool, or rivet gun to deform the headless end and hold the rivet in place. Due to its high reliability and level of safety, the solid rivet is widely used in the construction of aircraft, bridges, or steel structures. The solid rivet used for aircraft is mainly made of aluminum alloy, titanium, or nickel-based alloys.

What is the purpose of the two heads on each end of a rivet?
The two heads on each end of an installed rivet let it support tension loads (two forces pulling on opposite directions) and shear loads (the force is parallel to the surface or axis of the shaft). Solid rivets are one of the oldest, most popular and commonly used types of fasteners.
What is the head of a rivet called?
A rivet has a pre-formed head at one head, called the factory head. Another head is formed after insertion and it’s referred to as the shop head. The factory head is similar to the head at one end of a bolt while the shop head is like a nut, which forms a temporary head at the other end of a bolt.
What is the tail of a rivet?
The end of a rivet’s shaft, which is formed into the shop head is called the tail. The process for forming the tail into a head is known as upsetting or bucking, which means it is deformed. By doing so, the tail expands, allowing it to securely hold the rivet in place. The two heads on each end of an installed rivet let it support tension loads (two forces pulling on opposite directions) and shear loads (the force is parallel to the surface or axis of the shaft).

What is a Pop Rivet and How Does it Work?
A pop rivet is also known as a blind or hollow rivet and is used where you are only able to work with one side of the rivet. A special pop rivet gun or tool pulls the mandrel head into the body of the rivet, which then expands against the blind side of the join. Once it meets the face of the join’s blind side the mandrel snaps, causing the stem to eject to create a tight joint. A pop rivet can be used as a replacement for nuts and bolts, screws, welds and adhesives.
