Rivet Nut Countersunk Knurled Closed End, also referred to as Rivnuts, Blind Nuts, and blind threaded rivet nuts, are an internally threaded insert often used when the thickness of the application at hand is too small to tap a standard thread.

Using rivet nuts creates a vital thread in thin sheets of material for high-strength fastening from bolts and other threaded articles.

The full countersunk head is chosen over a reduced countersunk head type due to its more robust nature. 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.

The knurled body on the rivet nut provides excellent resistance to movement within the application than knurling under the head, especially when installed in softer materials. The closed-end blocks any form of contamination getting to the component and also prevents the use of screws that are too long for the application.

Installing these rivet nuts is simple: using a unique tool with a threaded stud, or nose, that engages with the internal threads of the rivet nut and pulls upwards, 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. Blind rivet nut setting tool install.

Rivet Nut Countersunk Knurled Closed End are available in diameters from M3 to M12 to suit various grip ranges.

Available at Juxin fasteners in zinc-plated steel, A2 stainless steel, and A4 stainless steel as standard.

Non-standard sizes and materials are available to order as specials, including small-volume manufacture, modifications, and bespoke parts made to drawings. Minimum order quantities apply.

Countersunk, Closed-end Knurled Rivet Nut Application Notes:

The grip range of these outserts can be affected by the type of sheet material being used. It is recommended that a few test installations be conducted to determine the appropriate grip range for your specific application. The countersunk head, knurled, European-style rivnut, is installed using pneumatic, hydraulic, or manual hand tools. The installation process is simple, easily controlled, and less labor-intensive than other processes associated with nuts and bolts. When properly inserted, the rivnut head will be flush with the surrounding sheet material.

These industrial fasteners will do the job for flush installation and excellent spin-out resistance. They can effectively reduce assembly costs by eliminating processes associated with the assembly of nuts and bolts.

The thread area is enclosed, which prevents leakage past the threads from either side of your application. These rivet nuts have a ribbed body to hold them in place when tightening a screw. The body and flange are zinc yellow-chromate plated steel for corrosion resistance. Install in a drilled hole using a rivet nut tool. The tool collapses the nut, creating a backside flange that holds the nut to the material. Length is measured from under the flange. Installed length is the maximum length of the barrel when installed.
