Reliable Threaded Fastening for Sheet Metal Assemblies - knurled thread insert

A cut-off rivet nut is a threaded fastening component designed for installation by riveting, providing an internal thread in sheet metal and other structural components. During installation, a dedicated rivet nut tool deforms the rivet nut body to create a secure clamping structure within the parent material. This process establishes a threaded connection for subsequent screw or bolt installation, making it a practical solution for applications where conventional tapping or welding may be less suitable.

Compared with directly tapping thin sheet metal, rivet nut installation can provide a dedicated threaded fastening point without requiring sufficient material thickness for a conventional tapped thread. It also eliminates the need for a welding operation, helping simplify assembly processes and reduce heat-related effects on surrounding components. Depending on the product design and installation method, rivet nuts can be used in assemblies where access to both sides of the workpiece is limited.

Cut-off rivet nuts can be selected according to thread requirements, body design, head configuration, material, and application conditions. They support efficient production assembly and provide convenient access for maintenance, component replacement, and subsequent fastening operations.

Technical Specifications

Key selection factors include metric or inch thread sizes, base material compatibility, head style, grip range, installation hole diameter, and surface finish. Depending on the intended application, materials may include carbon steel, stainless steel, or other suitable metals. Surface treatments can be selected based on corrosion resistance, appearance, and environmental requirements.

For reliable installation, the rivet nut must match the parent material thickness and the specified installation conditions. Thread dimensions, grip range, hole preparation, and compatible installation tooling should be verified against the product drawing and technical datasheet. Actual specifications depend on the selected model and customer requirements.

Applications

Cut-off rivet nuts are suitable for a wide range of industrial applications, including electrical enclosures, control cabinets, metal housings, automotive components, machinery, industrial automation equipment, and general sheet metal fabrication. They are particularly useful when a secure internal thread is required in sheet metal assemblies or when components need to be fastened and removed during maintenance.
