Rivet nuts, also known as rivnuts, provide a simple way to add a threaded insert to an inaccessible reverse side of a material surface.

Dorman Rivet Nut

When an original riveted connection fails, or when mounting aftermarket fenders, spoilers, racks or other accessories, this tubular steel rivet nut is a fast and simple way to ensure a strong connection between the surfaces of two materials. Precision-manufactured for an exact fit inside a predrilled hole, this 1/4-20 rivet nut anchors entirely from just one accessible side to create an internally threaded insert ready for bolting.
