Abstract
Abstract A fastening element for the flexible fastening of a part to a base includes an anchoring element such as a nail which is adapted to be power driven into the base and a coupling part having detents at one end which engage around coupling detents of the nailhead and an opposite end which is secured to a nut. The nut provides a threaded receptacle for a threaded bolt which is adapted to bear either directly or through a washer upon the part to be fastened.
