Solid/round head rivets A typical technical drawing of a universal head solid rivet There are several types of rivets, designed to meet different cost, accessibility, and strength requirements: The rivets themselves were essentially short rods of metal, which metalworkers hammered into a pre-drilled hole on one side and deformed on the other to hold them in place. Archeologists have also uncovered many Bronze Age swords and daggers with rivet holes where the handles would have been. Rivet holes have been found in Egyptian spearheads dating back to the Naqada culture of between 44 B.C.

However, it is much more capable of supporting shear loads (loads perpendicular to the axis of the shaft).įastenings used in traditional wooden boat building, such as copper nails and clinch bolts, work on the same principle as the rivet but were in use long before the term rivet was introduced and, where they are remembered, are usually classified among nails and bolts respectively. To distinguish between the two ends of the rivet, the original head is called the factory head and the deformed end is called the shop head or buck-tail.īecause there is effectively a head on each end of an installed rivet, it can support tension loads. In other words, the pounding or pulling creates a new "head" on the tail end by smashing the "tail" material flatter, resulting in a rivet that is roughly a dumbbell shape. On installation, the rivet is placed in a punched or drilled hole, and the tail is upset or bucked (i.e., deformed), so that it expands to about 1.5 times the original shaft diameter, holding the rivet in place. The end opposite the head is called the tail.
Before being installed, a rivet consists of a smooth cylindrical shaft with a head on one end. Brown (December 2014).Ī rivet is a permanent mechanical fastener.
Some rivets will even break off during installation.Permanent mechanical fastener Solid rivets Sophisticated riveted joint on a railway bridge Riveters work on the Liberty ship SS John W. Rivets are permanent fasteners, so you can’t easily remove them.
#Rivet bolt connections install
You can easily remove bolts after installing them you just need to use the same bit that you used to install the bolts but in reverse. Blind rivets, for example, typically require a special tool to install.īolts are temporary fasteners, whereas rivets are permanent fasteners. Rivets, on the other hand, may require a special tool.
#Rivet bolt connections driver
You can install bolts using a traditional driver with the appropriate bit. You can install rivets by inserting the smooth shank into a hole.Īnother difference between the bolts and rivets involves their installation. They still have a shank, but there’s no threading on the shank. The bolt’s threading will catch with the hole’s threading. You can install a bolt by driving it into a threaded hole.
Bolts are designed for use inside threaded holes. While they are both used to join two or more components, bolts and rivets aren’t the same. Blind rivets, conversely, are designed for fastening applications where you can’t access the back of a workpiece. Solid rivets consist of a solid shank and a head. Rivets can hold multiple components together, including aerospace components. They are used to hold components together. Like with bolts, they typically have a head at the top. Rivets are fasteners consisting of an unthreaded shank. If a bolt has a hexagonal head without a recess, you can use a hex socket bit to install it What Are Rivets? To install a bolt, you’ll need to use a bit that accommodates the bolt’s head. All bolts have a shank, which is either partially or fully threaded depending on the bolt type.Īt the top of a bolt is the head. The shank is the main cylindrical body of a bolt. What are bolts and rivets exactly, and how do they differ? What Are Bolts?īolts are fasteners consisting of a threaded shank and a head. Two of the most common types of fasteners used in the construction of airplanes are bolts and rivets. Fasteners are used to hold components together. Commercial jets, for instance, contain an average of 1.5 to 3 million fasteners. Fasteners are an essential part of all airplanes.
