UNDERCUT ANCHOR
An undercut anchor having an at least partially threaded rod portion having an outer thread diameter DROD. The anchor having an expansion feature coupled to the rod portion and an expansion sleeve having an outer diameter DOUTER SLEEVE, an inner diameter DINNER SLEEVE and a wall thickness TSLEEVE. Furthermore, the expansion sleeve has a plurality of circumferentially distributed fingers which are configured to flex outwards when a ramp portion of length LRAMP of each of the respective fingers is forced against the expansion feature during installation of the undercut anchor. The fingers each having a length LFINGER and a distance therebetween of WSLOT.
