Female thread anchor with metric thread for anchoring in hollow-core prestressed concrete ceilings
  • Screws or threaded rods can be used
  • The anchor can also be mounted outside the cavity axis, up to 50 mm from the prestressed strand – maximum flexibility
  • Quick, easy installation – no special tool required
  • Immediate load-bearing capacity – no waiting
Notice
  • The cone is separated from the expansion sleeve when the screw or hexagon nut is tightened. — Important: At least three screw/nut rotations are required. Applying the installation torque pulls the cone into the expansion sleeve and expands it.
  • Anchoring is only permissible in hollow-core prestressed concrete ceilings with a hollow space width that does not exceed 4.2 times the web width (bH <= 4.2 x bSt)
Proof of Performance
  • General technical approval Z-21.1-1832
  • VdS approval for fixings for stationary water extinguishing systems (approval no. G 412010)
  • Fire resistance (anchoring base: concrete C45/55 or C50/60): R30, R60, R90, R120: General technical approval Z-21.1-1832, fire protection test report no. (3526/3426)
