Abstract

The drilled hole(6) is filled with a hardening substance(5) so that after hardening of the substance the threads(4) of the screw(1) are embedded partially in the solid material(17) and partially in the mortar shell(13). The depth of penetration of the thread in the solid material is 30-50 per cent of the thread depth. The penetration depth of the screw is 5 to 10 times the screw's diameter. At the leading end of the screw shank(2) there is at least one slot(19) extending in the longitudinal direction.
