TheITS rivet nutsare fasteners designed to provide a metric thread in sheet metal and profiles using a single-sided installation system. Their cylindrical design andcountersunk headallow for a threaded fixing point with a geometry adapted for countersunk recesses.The ITS family is available in various metric sizes and sheet thicknesses, enabling the selection of the appropriate part based on material and assembly requirements.
ITS rivet nuts
The ITS model has a cylindrical body and countersunk head. It provides a metric thread in sheet metal and profiles and can be installed from one side of the component.
Unlike flat-head or reduced-head versions, the countersunk head is designed to sit inside a countersink machined into the workpiece, producing a flush finish.
ITS rivet nut features
- Cylindrical geometry.
- Countersunk head.
- Metric thread.
- Single-sided installation.
- Available for various sheet thicknesses.
- Manufactured in trivalent chromium (Cr III) zinc-plated steel and A2 stainless steel.
Materials and finishes
The rivet nut range includes various materials. For the ITS family, the catalog lists:
- Trivalent chromium (Cr III) zinc-plated steel.
- A2 stainless steel.
The catalog’s general technical data sheet specifies the steel asC1008and the stainless steel asAISI 304.

Applications
Rivet nutsITSare a solution for applications requiring athreaded connection on sheet metal or profileswhere access to the rear side of the workpiece is limited or impossible.
Their countersunk head design allows for use when the workpiece features a countersunk recess and the goal is to have the nut head sit flush with the material surface.
Advantages of countersunk rivet nuts
The main feature of the ITS family is itscountersunk head. This geometry allows the head to sit within the countersink in the sheet metal, distinguishing it from flat, reduced, or slotted head versions.
Installation from a single side allows for the addition of a metric thread even when the rear of the workpiece is inaccessible. Furthermore, the availability of various metric sizes and grip ranges makes it easy to select the right part for each application.
Mechanical data
The catalog includes various mechanical tests for rivet nuts, includingaxial load, breaking load, tightening torque, and shear strength tests.
For steel and stainless steel nuts, the specified axial load test values for the different thread sizes range from3,900 N for M3 to 34,000 N for M12. Shear breaking strength ranges from900 N for M3 to 6,500 N for M12.
Regardingtightening torque, the catalog table specifies values for the countersunk head configuration ranging from0.4 Nm for M3 to 24 Nm for M12for steel/stainless steel.
