The practical alternative to traditional plugs
The rock concrete screw is a special screw for anchoring in concrete and is subject to an application submitted for a European technical assessment for anchorages in crack 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.
Advantages and properties
• Installation without plugs • High extraction-resistance values
• No expansion effect, so smaller edge and centre distances are possible
• Broad range of applications thanks to a variety of screw heads and screw diameters
• An economical fastener → Time savings during installation → Cost savings in materials • Time-saving and straightforward installation → Setting and installation process performed in a single step
