Countersunk Head Rivet Nuts (Knurled body & closed end)

Full countersunk head rivet nuts with a knurled body and closed end, also referred to as Rivnuts, Blind Nuts and Nutserts®, are an internally threaded insert often used where the thickness of the application is too small to tap a standard thread. 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 presence of the knurled body on the rivet nut provides greater resistance to movement within the application than knurling under the head, especially when installed in softer materials, whilst the closed end blocks any form of contamination getting to the component. This also prevents the use of screws that are too long for the application.

The full countersunk head is usually chosen over the reduced countersunk type due to the stronger head. However, it is also deeper meaning it can only be used in material thicknesses greater than 1.5mm. Where the thickness of the application is smaller, the reduced countersunk type is often chosen instead. Both types offer a flush, finished appearance to the application.

Installing these rivet nuts is simple 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.
