Shaft with rotation locks, 3-part expansion body with metal tip. The dowel comes fully pre-assembled with a galvanized countersunk screw with TX drive. The metal tip allows for high holding values. It can be used directly thanks to the pre-assembled screw. In aerated concrete P2, it can be installed by simply hammering it in without pre-drilling. After setting the Apollo, be sure to tighten the screw - optimal holding values in aerated concrete are achieved after 6 screw turns. In hollow blocks and drywall, drill without impact while rotating to prevent the hole from becoming too large or the webs in the hollow block from breaking. It holds in concrete and solid brick through expansion, holds in hollow blocks through expansion and knotting, holds behind drywall through knotting, and in aerated concrete (gas concrete) creates a deep anchoring (knotting). Through-mounting.
