In sheet metal assembly such as thin sheets, chassis, and cabinets, traditional nuts often suffer from loosening, cracking, and complex installation. Aotuo’s Flare‑in Nut Z/ZS/NZ/NZS series is specially designed for thin‑sheet fastening. It achieves permanent locking through flaring technology, with high toughness, no sheet cracking, and easy installation, widely used in healthcare, automotive, electronics, communications, shipbuilding, aerospace, and traditional manufacturing.
Product Structure & Models
Flare‑in Nut comes in round and hexagonal shapes:
- Round: Z (carbon steel), ZS (stainless steel)
- Hexagonal: NZ (carbon steel), NZS (stainless steel)
Insert the nut into the pre‑punched hole, use a fixture to flare the non‑threaded section outward, and form a tight rivet with the sheet. No hardening is applied, ensuring high toughness and no cracking during installation, creating stable internal threads on thin sheets.
