Abstract
A fastening element is provided, in particular an expansion anchor, having a bolt and a retainer arranged on the bolt for introducing tensile forces into the bolt, the bolt having a first metal friction surface and the retaining element having a second metal friction surface, which is associated with the first friction surface. A coating in which particles, preferably hard particles, are embedded is arranged on at least one of the two friction surfaces.
