The ITSG and ITSCG rivet nuts are fasteners designed to provide a metric thread in sheet metal and profiles using a single-sided installation system. Their design combines a slotted cylindrical body with a countersunk head, offering a specific configuration within the Bearfix rivet nut range.
The range is available in various metric sizes and sheet thicknesses, allowing for the selection of the appropriate part based on material and assembly requirements.
ITSG and ITSCG Rivet Nuts
The ITSG and ITSCG models share a slotted cylindrical geometry with a countersunk head. The main difference is that the ITSCG model is the closed-end (blind) version.
- ITSG: Slotted cylindrical countersunk head rivet nut.
- ITSCG: Closed-end slotted cylindrical countersunk head rivet nut.
The combination of a slotted body and a countersunk head distinguishes this family from conventional cylindrical countersunk head versions.
Features of ITSG / ITSCG nuts
- Cylindrical geometry.

Materials and finishes
The rivet nut range includes various materials and finishes. For this family, the options are:
- Zinc-plated steel (Trivalent Chromium/Cr3).
- A2 stainless steel.
- The general catalog datasheet specifies the steel as C1008 and the stainless steel as AISI 304.

Applications
ITSG and ITSCG rivet nuts provide a solution for applications requiring a threaded connection on sheet metal or profiles where access to the rear side of the component is limited or impossible.
Their combination of a slotted body and countersunk head offers a specific configuration within the rivet nut range. The ITSCG version also features a closed-end (blind) body.
Advantages of slotted, countersunk-head rivet nuts
The key feature of this family is the combination of a slotted cylindrical body and a countersunk head. This geometry distinguishes them from unslotted countersunk-head versions.
The system enables the creation of a metric thread in sheet metal and profiles through installation from a single side. A variety of metric sizes and grip ranges allows for the selection of the appropriate part for each application.
Mechanical data
The catalog provides reference values for various mechanical tests performed on the rivet nuts, including axial proof load, ultimate tensile load, tightening torque, and shear strength.
For cylindrical, countersunk-head configurations, the axial proof load for steel and stainless steel reaches up to 34,000 N for the M12 size., while the shear strength reaches up to 6,500 N for M12. The values depend on the thread size, material, and nut configuration.
