Functioning - The FAZ II is suitable for pre-positioned and push-through installation also suitable for stand-off installation under certain conditions. - Prior to installation, place the hexagon nut in the optimal position (the drive-in pin projects by approx. 3 mm out of the hexagon nut). - When applying the torque, the cone bolt is pulled into the expansion clip and expands it against the drill hole wall. - The head embossing offers a simple control of the anchoring. - In the case of series installation, we recommend using the FABS bolt anchor setting tool.
