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 other additional components. During installation, the thread cuts a corresponding thread into 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 ratings
• 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:

• Adhere strictly to the specified installation parameters
• Only suitable for C20/25 to C50/60 grade concrete
• Screws regulated by ETA-15/0886
