Essve concrete screw 7.5x72 countersunk CS-100 C4 (100 pcs/pack)

Special hardened screw that is driven directly into a pre-drilled hole, without a plug. It is fully threaded with a so-called “hi-low” thread that makes installation easier. The screw is made of hardened steel with a bright zinc-plated or CorrSeal coating. 

The concrete screw is designed for fast and easy anchoring in concrete, brick, and perforated brick. In general, load capacity improves as the anchoring depth increases. When anchoring in materials other than concrete, a test fastening must be carried out in accordance with an assessment approved by the Swedish National Board of Housing, Building and Planning (Boverket) to determine the actual load capacity. The concrete screw has also been tested and approved for pulsating loads.
