- High-quality next generation Zn concrete screw
- Diameter according to drill size.
- Unique thread toothing bites into concrete efficiently and quickly.
- The special thread design makes it easier for the screw to bite into concrete, which adds up to a high pull-out value. The cost effective screw requires less fastening points.
- The hex also has a Torx head, except for the 6 mm screws.
- CE/ETA approved Eta Option 1 approval for cracked and uncracked concrete. Fire rating R120. C1 and C2 safety standards for seismically active areas.
- In the thicker dimensions, more available immersion depths facilitate using the same screw for fastening materials of varying thickness.
- The approval guarantees that the concrete screw can be pulled out from 20 mm depth twice and used to refix a max. 10 mm piece.

Application
- Recommended for push-through installation.
- No need to clean drill holes in floor and ceiling installations. When drilling into the floor, the hole must be 3 x deeper than the screw diameter.

Applications
Steel structures, handrails, element supports, shelf structures, stairways, tunnel structures.
6 mm concrete screws are excellent for HVAC installations (fastenings, rail systems, air conditioning installations and banding strips installations).
