KAPTI NUT® installation in four steps:
1. KAPTI NUT® fasteners are installed in a panel with a pre-pierced hole, by a single bow from a conventional press simple die tool underneath. The panel and the KAPTI NUT® are located onto the die pin. The taper on the pin centralises the panel hole and the KAPTI NUT®. This ensures the accuracy of positioning attributed to the KAPTI NUT®. The die pin is spring loaded and retracts into the die whilst maintaining the fastening position.
2. The KAPTI NUT® is pressed through the panel forming a tapered flange on the back. It is this formed flange which makes the panel rigid and contributes to the overall performance of the fastening.
3. When the KAPTI NUT® meets the internal form of the die tool, the leading edge is rolled back on itself to meet the flange. This creates a mechanical locking between the fastener and the panel. The unique square profile and radial splines interlock with the panel flange to provide a secure anti-rotational device. The top of the KAPTI NUT® is now flush with the panel. These three fundamental characteristics can be visually inspected eliminating any concerns around structural integrity.
4. The two parts are now locked providing a high strength threaded attachment point which can be used from either side.
