Proven million times and flexible - in price and performance. ETA Option 7 anchor bolt for push-through and pre-positioned installation.


  • FBN II offers maximum load-bearing capacity in non-cracked concrete
  • Reduced anchorage depth reduces drill time - this saves time and reduces reinforcement hits during drilling
  • Long thread allows stand-off installations and variable usable lengths
  • Diameter 8 to 20 mm also for reduced anchorage depths, e.g. for small loads or if reinforcement is hit
  • Embossed letter on the head for subsequent control of the installation as it indicates the setting depth
