What Are Rivet Nuts?
Rivet nuts, also known as threaded inserts or nut inserts, are tubular fasteners that create strong, permanent threads in thin materials like sheet metal where traditional threading would be impossible. These specialized fasteners feature a hex body design that prevents rotation during installation and accepts various thread sizes based on application requirements.
Application Considerations
Selecting appropriate rivet nuts requires evaluating several critical factors to ensure proper performance. The grip range must match your parent material thickness, as insufficient grip prevents proper installation while excessive grip causes incomplete expansion.
Thread pitch compatibility with mating fasteners ensures proper engagement and prevents cross-threading issues. Sheet metal applications benefit from large flange designs that distribute loads and prevent pull-through failures.
