Concrete screw BTS ST 10-90/5, countersunk TX50 A4

The concrete screw BTS ST 10-90/5 is optimally suitable for a wide variety of heavy-duty applications in cracked and non-cracked concrete according to the ETA-assessment Option 1. It achieves the highest loads combined with easy mounting (use of an impact wrench is recommended), obtains fire resistance class R 120 for even more safety in case of fire, is approved for use under seismic action (C1 valid for a setting depth of 85 mm) and may even be used to fix fire extinguishing pipe systems to concrete ceilings according to VdS guidelines. Because of the three setting depths and the adjustability, the screw can be used in many applications. The concrete screw as an expansion-force free anchor is also ideal for temporary fixings as it can be removed completely. The countersunk screw has a TX drive for fast mounting and consists of stainless steel A4 for higher corrosion resistance.
