3-part split dowel body without dowel cap, with rotation locks on the dowel neck and dowel body to prevent twisting in the building material. TRI + screw: countersunk screw with PZ drive. Additional information: Create a drill hole the size of the dowel diameter. Drill in hollow blocks and drywall without impact in rotary mode to prevent the webs in the hollow block from breaking out. The drill hole in drywall should be made with a wood or metal drill bit. Drill with impact in concrete and solid stone. Minimum screw length = dowel length + component thickness + 1x screw diameter. Pre-mounting and through-mounting 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 dowel must be adhered to. Drilling methods and hole cleaning must be adapted to the building material. The recommended loads apply to mounting in the building material, not for mounting in joints. For safety-critical fastenings, approved dowels must be used. For items with an included screw, any differing values on the packaging must be observed. The holding value applies to fastening in aerated concrete PP4.
