Different Head Styles and Body Styles of Rivet Nuts

Rivet nuts have some head styles

1. A wide front-side flange provides a large load-bearing surface. This reinforces the hole and prevents push-through. It’s also possible to apply a sealant beneath the flange for weatherproof applications.

2. A thick flange can act as a spacer and provide some extra push-out strength.

3. Countersunk and low-profile heads ensure flush or near-flush installation, such as countersunk head round body rivet nut.

4. Wedges or knurls underneath the head are designed to bite into the mating material and keep the fastener from turning in the hole, such as small countersunk head knurled body nuts.

Rivet nuts have several body styles

In order to prevent the fastener from spinning in the hole at high torque levels, especially in aluminum, plastic or other soft materials, steel rivet nuts come in many body styles. Apart from the cylindrical body with a smooth surface, there are splined, square and hexagonal bodies available.
