Rock Concrete Screw with Countersunk Head (7.5x120mm; TORX 40)

Rock concrete screw, countersunk head

Material:

• Galvanized steel
  

Description:

The Rock concrete screw is a practical alternative to traditional anchors. This specialized screw is designed for anchoring in concrete (from C20/25 to C50/60 grade concrete) and has European Technical Assessment (ETA) for anchors in cracked and non-cracked concrete. The Rock concrete screw is installed directly into the drilled hole without the need for an anchor or any additional components. As it is screwed in, the thread cuts a corresponding thread in the base material. This type of installation is not only very simple but also ensures minimal installation time and maximum cost savings. The high-strength screw steel, extremely complex hardening process, and specialized thread ensure that the Rock concrete screw performs reliably even in C50/60 high-strength concrete.

Advantages and Features:

• Installation without anchors
• High pull-out resistance values
• No expansion effect, allowing for smaller edge and center distances
• Wide range of applications due to various screw heads and diameters
• Cost-effective fastening
• Time savings during installation
• Material cost savings
• Fast and simple installation
• Installation and setting in one step

Notes:

• Strictly adhere to the specified installation parameters
• For use only in C20/25 to C50/60 grade concrete
• Screws regulated by ETA-15/0886
