Abstract
A process and device are described by which means fastening elements are mounted onto one side of a composite panel. The rigid fastening element has an expandable claw at its head which is placed in a recess in the composite panel by using a conventional rivet gun for dummy rivets, fitted with a special accessory; the fastening element, which may be in the form of a bolt with a countersunk head, is drawn back and the expandable claw prevented from moving with it, whereupon the claw opens out and is anchored firmly in the core of the composite panel.
