In thin‑sheet assembly scenarios such as sheet metal, chassis, cabinets, electronic equipment and communication devices, traditional threaded connections often suffer from loosening, thread slipping, insufficient torque and complex installation. Aotuo Hexagon Self‑Clinching Studs NFH / NFHS series are specially designed for thin‑sheet fastening. With hexagon anti‑rotation structure and clinching technology, they deliver high torque, high reliability and fast installation, widely used in automotive, electronics, industrial control, telecommunications, home appliances and general machinery manufacturing.
Product Overview
NFH / NFHS hexagon self‑clinching studs are pressed into pre‑punched holes using a riveting press, forming a rigid interlock with the sheet. After installation, the back stays flat with no protrusion, loosening or rotation, providing stable external thread connection points on thin plates.
- NFH: Carbon steel, heat treated and zinc plated
- NFHS: SUS304 stainless steel, corrosion resistant, high temperature resistant, vibration resistant
Key Specifications

Core Advantages
- High torque resistance: Hexagonal structure prevents spinning; strong torque capacity, resistant to slipping and loosening.
- Permanent fastening: Integrated with the sheet after clinching, shockproof and vibration resistant, no falling off in long‑term use.
- Efficient installation: No welding, tapping or secondary processing; single‑step fast clinching, ideal for automated lines.
- Flush mounting: Panel remains flat after installation, saves space and ensures clean appearance.
- Full range: Covers mainstream metric and imperial sizes to meet diverse design requirements.
Typical Applications
Chassis & cabinets, telecommunication equipment, automotive parts, home appliances, electronic control modules, instruments, sheet metal structures and other thin‑sheet fastening scenarios.
