Sleeve anchors are an anchoring solution made from steel and stainless steel for cracked and non-cracked concrete and in applications exposed to seismic loads. The low level of energy required to hammer in the fixings allows for a force-saving mounting process. In addition, the optimum interaction of the screw shank and anchor sleeve enables a high shear load resistance. The drill hole is made, the anchor is hammered in, and the screw is tightened with a controlled torque. The expansion sleeve expands against the wall of the drill hole. The anchors use friction locking to safely introduce the loads into the base material.
