The “POWERDRIVE WALL” scaffolding anchor, made of pure nylon, is used
in combination with the Hüfner “EYE” eye screw (Ø 12 mm). A special thread guide
reduces the torque required for the eye screw by up to 35%. A second thread guide
at the lower end of the anchor prevents elongation
of the anchor and improves overall pull-out resistance. Tensile strengths of up to
21.5 kN were achieved in MZ12/20 bricks. The Hüfner “RING”
and “KREUZ” cover caps complete the system.
