Concrete Screw ECS
Concrete Screw, Hex Head with Flange CorrSeal
Class for corrosion resistance:
C4 for outdoor use
A hardened concrete screw that is installed directly into a pre-drilled hole, without a plug. It has hi-low thread technology that provides excellent load capacity and drives easily into the substrate. The CorrSeal surface treatment gives a minimum lifetime of 15 years in outdoor environments in corrosivity category C4 according to Swedish national type approval. According to ISO 9223 corrosivity category C4 corresponds to outdoor installation with high amounts of air pollution or moderate amount of salt, e.g. industrial and coastal areas.
ESSVE Concrete Screw ECS is an affordable concrete screw for simpler applications where the assembly does not require approvals e.g. ETA approval.
When mounting, an impact driver is recommended. The concrete screw does not require a preload torque to ensure the fixing, which means that when the screw has reached the surface, all additional tightening must be avoided. The final torque applied shall not be greater than that required to hold what is to be fixed in place. The tightening torque specified is the maximum torque, not to be confused with other products that require a preload torque (e.g. wedge anchors). Concrete screw ECS is hardened and therefore sensitive to mounting that is not perpendicular. The drill hole shall be 90 degrees to the substrate. Concrete screw ECS has no requirement for drill hole cleaning before installation, however the hole must be deep enough that the correct setting depth is reached even with the extra dust that remains in the hole.
