ABSTRACT:
A fastening plug for mounting furniture hardware having an expandable sleeve into which an elongated shaft of an expander enters, the shaft having a head for rotating the expander relative to the sleeve. The elongated shaft of the expander has multiple expansion sections along the length of the shaft and which taper in the direction of the protruding end of the shaft. The central bore of the sleeve which receives the elongated shaft of the expander, is shaped so as to complement the shaft, and the position of the complementary, tapering expansion sections of the shaft is varied relative to the complementary tapered central bore sections in the sleeve when the expander is rotated relative to the expansion sleeve.
