EJOT® Concrete screw JC2 for cracked and non-cracked concrete

Concrete screws are true all-rounders and have the great advantage that they are removable. Since there are hardly any expansion forces, they are particularly suitable for temporary fastenings near the edge. Due to their multiple gear cutting in the surface, they can also be used for pre-stressed hollow core slabs (ETA-18/0221).

The concrete screw is screwed directly through the attachment in the drill hole. By doing so, the thread cuts into the concrete, creating a mechanical locking mechanism over the total embedment depth.

The ETA regulates the usability of the concrete screw for cracked and non-cracked concrete indoors. Beyond that, the fire rating R 120 guarantees additional safety.
