Rivet Nut

A rivet nut, also known as a blind rivet nut or threaded insert, is a type of fastener that provides a threaded hole in a material that is too thin to be tapped for a conventional screw or bolt. It is commonly used to attach components where it is impractical or impossible to use traditional nuts and bolts. Rivet nuts are versatile and can be used in a variety of materials, including metals, plastics, and composites.

How Rivet Nuts Work

Rivet nuts work by being inserted into a pre-drilled hole in the host material. They have a cylindrical body with external threads and either a smooth or knurled surface that helps prevent spinning. At one end, there is a flanged head that prevents the nut from being pulled through the hole, and at the other end, there may be a closed or open end depending on the design.

To install a rivet nut, a special tool is used to pull a mandrel through the body of the rivet nut, causing the back end to deform (bulge) and clamp against the back side of the material. This creates a strong and reliable threaded mounting point.

Advancements of Pressure Rivet Nuts

Enhanced Materials

High-Strength Alloys: Advances in materials science have led to the development of pressure rivet nuts made from high-strength alloys and composites, improving their load-bearing capacities and durability.

Corrosion-Resistant Coatings: New coatings and treatments enhance resistance to corrosion and wear, extending the lifespan of rivet nuts in harsh environments.

Improved Design Features

Multi-Threaded Designs: Innovations include multi-threaded pressure rivet nuts that offer increased grip and load distribution, reducing the risk of stripping and enhancing performance in high-stress applications.

Reduced Installation Forces: New designs have optimized the geometry of pressure rivet nuts to reduce the force required for installation, improving ease of use and reducing tool wear.
