An adaptor for setting a self-drilling, chemically anchorable, fastening element () includes a rotor member () rotatably supported in the adaptor housing () and having at its opposite ends () respectively, a coupling section () for connecting the rotor member () with a drilling tool () for joint rotation therewith, and a coupling receptacle () for fixedly receiving a free end () of the fastening element (). Support elements () are provided in one of two housing parts () for rotatably supporting the rotor member (). Sealing elements (), which are provided in another housing part (), for a connection channel section () that connects a connection opening () in the housing () for the ejection medium () with a feeding channel () in the rotor member ().

Adaptor for setting a self-drilling, chemically anchored, fastening element

A fastening element has a drilling head () provided at one end () of anchor tube () and having at least one inlet opening () that opens toward the receiving chamber () of the anchor tube (), and at least one through-opening () that opens outwardly for passing of the hardenable mass therethrough, and a mixing element () for the hardenable mass and which is located in the drilling head () between the at least one inlet opening () and the at least one through-opening ().

Fastening element

The invention provides low molecular weight or polymeric organic materials in which at least one hydrogen atom is replaced by a group of the formula (A) where R is alkyl group, alkoxyalkyl group, alkoxy group, thioalkoxy group, aryl group or alkenyl group, in each of which one or more hydrogen atoms may be replaced and one or more nonadjacent carbon atoms may be replaced.
