Hex Nutserts
Hexagon shape nutserts for maximum resistance to unscrewing.
A hex-shaped nutsert provides the highest twist resistance of any nutsert option. Hex nutserts are designed for use in punched hex shape holes using a nutsert tool. The tool collapes the nut, creating a backside flange that holds the nut to the material. Wide range online in Australia, check out the nutsert blog.
