A clinch nut (also known as a press-in nut, captive nut, Self-Clinching Nuts or S-nut) typically consists of a round body rather than the hex geometry commonly associated with loose nuts.
While the nut is most common and imortent fastener , clinch nuts is spcial nut for the thin plated connect.
Round Self-Clinching Nuts are installed by inserting them into a pre-drilled hole and then using a specialized riveting tool to expand the unthreaded portion of the nut, creating a permanent mechanical bond with the host material. This process eliminates the need for welding, tapping, or back-side access, making them ideal for:
1. Electronics and Enclosures
- Computer server racks, telecom equipment cabinets, and power supply housings
- Consumer electronics such as washing machines, refrigerators, and air conditioners
- Lightweight aluminum or sheet steel chassis requiring secure fastener points
2. Automotive Industry
- Interior panels, door trims, and dashboard components
- Battery enclosures and electric vehicle (EV) structural parts
- Applications where weight reduction and corrosion resistance are critical (often using aluminum or stainless steel rivnuts)
3. Aerospace and Defense
- Aircraft interior fixtures, avionics mounting brackets, and cabin components
- Satellites and UAV (drone) structures—where precision, low profile, and single-sided installation are essential
4. Furniture and Retail Displays
- Modular shelving systems, display stands, and office furniture
- Quick-assembly products requiring strong yet removable connections
5. Construction and Architectural Metalwork
- Aluminum curtain walls, signages, and decorative metal panels
- Prefabricated building components where on-site welding is impractical
6. Medical and Industrial Equipment
- Stainless steel medical carts, diagnostic device enclosures
- Cleanroom-compatible fasteners that avoid contamination from welding fumes
- Single-sided installation: No need for access to the back of the workpiece.
- High pull-out and torque resistance: The expanded body creates a tight interference fit.
- Versatility: Compatible with steel, aluminum, plastic, and composite materials.
- Aesthetic finish: The rounded head provides a smooth, flush appearance when installed.
Round Self-Clinching Nuts are commonly specified to standards such as IFI-114, DIN 985, or ISO 14580, and are available in materials like steel, stainless steel (304/316), and aluminum.
