Rivet Nut Flanged Full Hex Closed End

Rivet Nut Flanged Full Hex Closed End, commonly known 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. The use of these rivet nuts creates a strong thread in thin sheets of material for high strength fastening from bolts and other threaded articles.

The full countersunk head is often chosen over a reduced countersunk type due to its stronger head. It is also deeper, meaning it can only be used in material thicknesses greater than 1.5mm – offering a flush, finished appearance to the application.

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 to the component. This also prevents the use of screws that are too long for the application.

Installing these rivet nuts requires the use of a special tool with a threaded stud which engages 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 thin sheet material.
