Rivet Nut

A rivet nut is a blind-installed internally threaded insert that forms a reusable thread in thin sheet or hollow sections. It provides a captive thread for panels, cabinets, vehicle bodies, appliances and fabricated enclosures. The installation process uses a mandrel to pull the threaded section, causing the body to collapse behind the sheet and clamp the insert in place, creating a secure attachment point. This component is commonly used in applications where access to the rear side is limited, allowing for strong threaded connections in materials that are too thin to be tapped directly.

Buyers should specify thread, body style, head type, grip range, hole size, material, installation force and spin-out/pull-out data. These parameters are critical for ensuring proper fit and performance. The material options on file include steel, stainless steel, and aluminium alloy, each offering different properties such as corrosion resistance and strength. Surface finishes may include zinc-plated, passivated, or material-specific options, which should be confirmed against the selected standard and supplier evidence.

Standards listed here govern particular forms and do not make sizes, materials or finishes interchangeable. The RFQ should state the exact standard or drawing, required configuration, quantity and inspection evidence. It is essential to verify model-specific values and standards with the legal manufacturer or supplier before procurement. The directory provides reference ranges, not guarantees of compliance or certification. Always confirm the applicable standard, nominal size, material, strength/performance data, surface finish, and RFQ selection fields against the actual product and application requirements.

The installation mandrel pulls the threaded section so the body collapses behind the sheet and clamps the insert in place. This creates a permanent, reusable thread that can withstand repeated assembly and disassembly. The blind installation allows for secure fastening in hollow or thin materials where access is limited. Proper installation requires correct hole size and grip range to ensure the body deforms properly and achieves the required pull-out and spin-out resistance. Maintenance signals include loosening of the thread or visible deformation of the surrounding material, indicating potential failure. The insert is not intended for high-load structural applications unless specified and verified.
