How do steel rivets work

Friction-lock rivet — Available as countersunk or dome shaped, these early forms of blind rivet where the first to be widely used in aerospace applications these rivets resemble an expanding bolt. Oscar rivets — Similar to blind rivets, Oscar rivets have splits along the hollow shaft.

These splits, which usually come in sets of three cause the shaft to bend and flare outwards as the mandrel is drawn into the rivet. The flare creates a wide surface which reduces the chance of the rivet being pulled out. Self-piercing rivets — These rivets do not need a drill or punched hole as the end includes a chamfered poke to pierce materials to be joined. Self-piercing rivets go through the top sheet of material but do not fully pierce the bottom sheet, creating a water or gas-tight joint.

Solid rivets also known as round head rivets — A technique that goes back to the Bronze Age, making this one of the oldest and also one of the most reliable types of fasteners.

Structural steel rivets — This type of rivet was widely used to join structural steels, but has been largely replaced by the use of high-strength bolts as they do not require skilled workers to install and tighten these bolts.

There are four basic types of rivets; tubular, blind, solid and split. There are two basic types of threaded inserts; press-in and blind. Also featured are a number of special rivets and fasteners on this page. Click on any of the rivets above for available dimensions and additional information.

Let us help. Rivets are the unsung heroes of the manufacturing industry. Rivets offer supreme fastening capabilities for light and heavy duty applications alike They are highly safe and reliable fasteners, with proven effectiveness in critical applications.

For these reasons, they are widely used in the construction of aircraft. In such cases, a form of hammer and anvil are required to form the factory head of a solid rivet. Both sides of the hole also require access for installation, so that the anvil is against one end of the rivet and the hammer strikes the other end. Hand hammers are rarely used for this process. Instead, modern manual riveting operations use hand-held air hammers. Automated drilling and riveting machines are also typical in aerospace manufacturing.

These incorporate hydraulic or electromagnetic presses. Semi-tubular rivets are solid over the main part of the shaft, which carries the shear load, but are hollow at the shop end to make it easier to form the shop head.

In construction industries, such as when joining steel structures for bridges or steel-framed buildings, solid rivets have largely been replaced by bolts. This is because rivets are more time-consuming to install and remove, offering limited clamp load.
