TheITR and ITRC rivet nutsare fasteners designed to add a metric thread to sheet metal and profiles using a single-sided installation system. Their cylindrical design andreduced headallow for the creation of a threaded fixing point while maintaining a more compact external profile.
The range is available in various metric sizes and sheet thicknesses, allowing the appropriate part to be selected based on material and assembly requirements.
ITR and ITRC rivet nuts
TheITRandITRCmodels share a cylindrical geometry with a reduced head. The main difference is that the ITRC model is theclosed-endversion.
- ITR:cylindrical rivet nut with reduced head.
- ITRC:closed-end cylindrical rivet nut with reduced head.
This configuration allows for the addition of a metric thread to sheet metal and profiles, with installation performed from a single side of the component.
ITR / ITRC nut features
- Cylindrical geometry.
- Reduced head.
- ITRC version with closed end.
- Metric thread.
- Single-sided installation.
- Available for various sheet thicknesses.
- Manufactured in steel and stainless steel, depending on the part number.
Materials and finishes
The catalog’s range of rivet nuts includes various materials and finishes. For this family, the following are specified:
- Zinc-plated steel (Cr III).
- A2 stainless steel.
The catalog’s general technical data sheet identifies the steel asC1008and the stainless steel asAISI 304.

Applications
The rivet nutsITR and ITRCare designed for applications requiring athreaded connection on sheet metal or profileswhere access to the rear side of the workpiece is limited or impossible.
Their cylindrical, reduced-head design provides a threaded fixing point with a more compact external profile. The ITRC version also features a closed-end configuration.
Advantages of reduced-head rivet nuts
One of the distinguishing features of this family is itsreduced head. Compared to standard flat-head versions, the ITR geometry features a smaller-diameter head while maintaining the cylindrical body shape.
The system enables the creation of a metric thread in sheet metal and profiles through single-sided installation. The availability of various metric sizes and thickness ranges facilitates the selection of the right part for each specific application.
Mechanical data
The catalog provides reference values for various mechanical tests performed on the rivet nuts, includingaxial proof load, ultimate tensile load, tightening torque, and shear strength.
For steel and stainless steel, the axial proof load listed in the catalog reaches up to34,000 N for M12, while the shear strength reaches up to6,500 N for M12. Values vary depending on the metric size, material, and nut configuration.
