A rivet is a type of fastener that is used to hold a product or workpiece together permanently. They have a bolt-like design and are attached to the shaft with a head that is broader than the shaft. When a rivet is hammered into a product or workpiece, the shaft, also known as the tail, expands to one-and-a-half times its original size, locking the rivet in place. However, there are various types of rivets utilised in the industrial business, including the ones listed below. But first, let’s clear up some concepts about what a rivet is.
What exactly is a rivet?
A rivets is a mechanical fastener with a head on one end and a cylindrical tail on the other end that resembles a metal pin. Rivets are non-threaded fasteners made of steel or aluminium. Before being inserted, rivets are constructed consisting of a smooth cylindrical shaft with a head at one end. The head’s opposite end is the tail.
The rivet is put into a punched or drilled hole, and the tail is tightened or buckled such that it protrudes about 1.5 times the diameter of the original shaft, fastening the rivet. To put it another way, hammering or tugging forms a new “head” by splitting the “tail” material on the other end flatter, resulting in a dumbbell-sized rivet.
Types of Rivets and its uses
Solid rivets, sometimes known as round rivets, have a long history, with some of the earliest specimens reaching back to the Bronze Age. They have a classic design that includes a shaft and a head. Manufacturers employ crimping to place solid rivets, which causes the shaft to bend and expand after being pressed into the product or workpiece.
Structural Steel Rivets
Structural steel rivets are similar to solid rivets in appearance, but they’re made for high-stress commercial building applications. They’re made of steel and are used to create bridges, high-rise buildings, storage sheds, and other structures. Prior to installation, structural steel rivets are usually heated in a furnace to make the metal softer, more flexible, and simpler to work with.
Split rivets have a one-of-a-kind design where the shaft divides in two directions. When a split rivet is pushed into a product or workpiece, the shaft extends in opposing directions, similar to a wall anchor. Split rivets are appropriate for use in products and workpieces made of flexible materials such as plastic or wood because of this.
Blind rivets, also known as pop rivets, are made up of a rivet and a mandrel. During installation, a tool called a riveter is used to control the mandrel, allowing the rivet to flex and expand into the product or workpiece.
Most rivets protrude from the object or workpiece after insertion. Flush rivets, on the other hand, are named for the fact that they sit flush with the object or workpiece in which they are inserted. Flush rivets, also known as countersink or countersunk rivets, are utilised in industrial applications that prioritise aerodynamics. They minimise drag and increase aerodynamics by sitting flat with the product or workpiece.
Once the shaft goes far enough into the product or workpiece, friction rivets are meant to lock into place. A friction rivet’s shaft does not expand until it is driven deep into the product or workpiece, unlike most other rivets.
