  • Substrate type: cracked concrete, non-cracked concrete and stone.
  • *Recommended tension load (C20/25 uncracked concrete): 3.57kN (M8); 5.71kN (M10); 9.52kN (M12); 16.67kN (M16).
  • *Recommended tension load (C20/25 cracked concrete): 1.98kN (M8); 4.29kN (M10); 5.71kN (M12); 9.52kN (M16).
  • Partial safety factor: 1.80 (M8); 1.50 (M10 and above).

*Apply to single anchors correctly installed at maximum embedment depth. Include partial safety factor of 1.80 (M8) and 1.50 (M10 and above) and an overall partial safety factor for action of 1.4, which depends on the type of loading and shall be taken from national regulations.
