Rivet Nut Countersunk Knurled Open End, often referred to as Rivnuts, Blind Nuts, or blind nut riveter kit, is a form of internally threaded insert that is used in applications where the material thickness is too small to tap a conventional thread.

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

The countersunk head is often chosen as it will sit flush within the application, leaving an aesthetically pleasing flat and smooth finish. The full countersunk head of this rivet is stronger than the reduced countersunk type but is also more profound, meaning that it can only be used in material thicknesses greater than 1.5mm. Use the blind rivet nut setting tool to install.

The knurled body of the countersunk rivet provides increased resistance to turning in the application, especially when installed in softer materials. The open-end style allows the stud or male threaded component to thread through the rivet nut without limiting the length or protrusion of the male threaded part.

Installed with a unique tool, these Countersunk open-end rivet nuts with a knurled body are engaged by the tool’s threaded stud, which pulls upwards and deforms the unthreaded section of the rivet nut, causing expansion under the reverse side of the material and provides a high strength permanent thread in thin sheet material.

Available from Juxin fasteners in materials and finishes that include zinc-plated steel, A2 stainless steel, and A4 stainless steel.

Available in diameters ranging from M3 to M12 to suit various grip ranges.

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 head inserts offer a flush flange, meaning the head “disappears” into the material, giving it a smooth surface.

Fast Facts:

Blind hole, one-sided installation capability.

Provide load-bearing threads in sheet materials.

Offers a flush flange and a smooth surface.

Good for applications where the clamping load is limited.

Available in aluminum, steel, and stainless steel.

The countersunk head, knurled, European-style RV nut is an ideal choice for those applications that require a flush installation. The unique knurling increases spinout resistance. They are well suited for use in various sheet materials and require no special tooling for installation. These industrial fasteners are available from Juxin Fasteners at very competitive pricing.
