Spiral-shaped expansion body with extra long shaft lengths for bridging thick, non-load-bearing layers. Foldable anchor cap. Anti-rotation devices on the anchor neck prevent rotation in the building material. Screw with PZ drive. Deep-lying anchoring in aerated concrete. Holds in almost all building materials. Automatically knots or expands depending on the building material. Wide range of applications due to different shaft lengths. Foldable anchor cap prevents deeper slipping. Spiral shape enables high holding values. Drill hole the size of the dowel diameter. Drill into perforated brick and gypsum plasterboard without percussion in a rotary motion to prevent the drill hole from becoming too large or the webs in the perforated brick from breaking out. Use a wood or metal drill to drill the hole in plasterboard. Drill into concrete and solid stone with percussion. Minimum screw length equals anchor length plus attachment thickness plus 5 mm. Pre- and through-fixing possible. Suitable for building materials such as concrete, solid brick, vertically perforated brick, raw density, hollow block, aerated concrete, gypsum plasterboard, and gypsum fiberboard.
