Expansible rawplug for walls and the like

摘要

Expansible rawplug for walls and the like whose ratio between diameter and the distance between two adjoining teeth is between 2.5 and 4.5, and whose end inside the wall in the longitudinal direction of the rawplug devoid of teeth is equal to or less than the diameter, thus improving its anchorage conditions, both in walls made of solid materials and walls made of hollow materials.
