The rock concrete screw is a special screw for anchoring in concrete (C20/25 to C50/60 normal concrete) and is covered by a European Technical Assessment for anchorages in cracked and non-cracked concrete. The rock concrete screw is screwed directly into the drill hole without a plug or other additional components. As it is screwed in, the thread cuts a mating thread into the subsurface. This type of installation is not only very easy, but also impresses with its minimum assembly time and maximum cost savings. The high-strength screw steel, an extremely complex annealing process, and a special thread ensure that the rock concrete screw also works reliably in class C50/60 high-strength concrete.
