How Is Aluminum Rivet Nut Different From Other Fastener Types?

As we all know, steel rivet nuts consist of a smooth cylindrical shaft with a head on one end, with the end opposite the head usually called the buck-tail, which are different from other types of fasteners. How does a steel rivet nut work? When it is installed in a drilled hole, the tail is bucked or deformed, meaning it expands about 1.5 times the original shaft diameter and securing that place. These are especially effective fasteners when it comes to supporting shear loads, although it can also support tension loads. There are some common types of aluminum rivet nut, each designed to meet different cost, accessibility, and strength requirements.

Round head rivets

They are used in applications that stress reliability and safety, most commonly used in assembling modern aircraft.

Semi-tubular rivets

They are alike to round rivets except for a partial hole at the tip, which is used to cut amount of force needed for application.

Blind rivet nuts

Tubular rivets that are supplied with a mandrel in the center, Specially designed tool must be used to draw the mandrel into the rivet, it can be installed in a joint from only one side of a part.

Drive rivets

Type of blind rivet that has a short mandrel protruding from the head.

Flush rivets

Utilizes a countersink hole so it can effectively be used on external metal surfaces that must good appearance.
