Secure sleeve anchor for high loads in non-cracked concrete
For heavy-duty fixings in non-cracked concrete the forced expansion anchor ZA B with bolt and hex-head screw is the optimal solution. This is confirmed by the ETA assessment Option 7 for non-cracked concrete for ZA 12. Due to the low setting torque and the low setting depth installation is quick and easy. The groove in the sleeve serves to tighten the connecting part firmly to the concrete surface, so-called hollow layer bridging. A setting depth marking is also provided for convenient installation. The high-quality metal anchor is made of steel quality 8.8 and offers the advantage of force controlled spreading of the sleeve when the screw or the nut is tightened in the drilling hole. The forced expansion anchor ZA comes in type ZA S (with hex-head screw) and ZA B (with bolt and hex-head screw).
