"The FH II is suitable for pre-positioned installation.
The internal thread bolt is turned when mounting with a hexagonal wrench. The cone is pulled into the expansion sleeve and expands it against the drill hole wall. At the same time, the anchor is pulled together by compressing the black, plastic ring.
There is a safe gap to the concrete surface.
The anchor complies with the approvals when the safe gap is 3--5 mm.
Alternatively, installation torque Tinst can also be applied.Just test it!
