Concrete screws unite top load-bearing capacity and fast installation. The approved steel and stainless steel versions enable use in cracked and non-cracked concrete, indoors and outdoors, and in areas subject to seismic influences. The screw solution is ideal for temporary anchors and is easy to dismantle. Furthermore, fixtures and constructions made from metal and wood can be perfectly anchored safely and permanently. The European Technical Approval and classification into fire resistance class R 120 ensure even more safety.
