Drill in hollow blocks and drywall without impact in rotary mode to prevent the ribs in the hollow block from breaking out. The drill hole in drywall should be made with a wood or metal drill. Drill with impact in concrete and solid stone. Minimum screw length = anchor length + component thickness + 1x screw diameter. Pre-assembly and through-assembly are possible. The specified holding values refer to screws with the largest screw diameter. Thread formation similar to DIN 7998. The anchoring depth of the anchor must be maintained. Drilling method and hole cleaning must be adapted to the building material. The recommended loads apply to installation in the building material, not for installation in joints. For safety-relevant fastenings, approved anchors must be used. For items with an included screw, any differing values on the packaging should be noted.
