Fastening device for securing wear-resistant tiles to a backing

摘要

A tile which forms part of a wear-resistant lining that covers a metal backing has a tapered hole and is held against the backing by a fastening device which fits into the tapered hole. The fastening device includes a threaded element that projects from the backing into the hole and an anchor that threads over the threaded element. The anchor fits completely within the tapered hole and has a tapered side wall, the taper of which corresponds to that of the hole.
