Flange Head Rivet Nuts (Knurled body & closed end)

Flange head rivet nuts with a knurled body and closed end (also known as Rivnuts, Blind Nuts and Nutserts®) are internally threaded inserts used in applications where the material (wall) thickness is too small to tap a conventional thread, therefore by using rivet nuts a strong thread is created in thin sheets of material for high strength fastening from bolts and other threaded articles.

The large diameter of the flanged head is used to reinforce the hole and increase resistance to pull-out, making this style of head ideal for load bearing applications. The closed end is used in applications to reduce corrosion from moisture or contamination, whilst also preventing screws that are too long from being used in the application.
The knurled body of the countersunk rivet nut helps prevent rotation within the application, especially when installed in softer materials, providing extra resistance to vibration than the smooth body version.
Flange head rivet nuts with a knurled body and closed end are installed using a special tool with a threaded stud (nose) that engages with the internal threads of the rivet nut and pulls upwards, in turn deforming the unthreaded section of the rivet nut to expand under the reverse side of the material, providing a high strength permanent thread in a thin sheet material.
