Concrete Screw ECS-HF Hexagon Head With Flange 6.3x30mm Corrseal C4 100pcs Essve

Description

Throughly hardened screw that is driven directly into a drilled hole, without a plug. It has a so-called hi-low thread that provides good load values and facilitates installation. The CorrSeal surface treatment provides at least 15 years of durability in corrosivity class C4 according to Swedish type approval. According to ISO 9223, corrosivity class C4 is characterized by outdoor environments with significant amounts of air pollution or moderate amounts of salt, e.g. industry and coastal areas. Essve Concrete Screw ECS is assessed in the Construction Product Assessment with Assessment Totally Accepted. Essve ECS Concrete Screw is an affordable concrete screw for simpler applications where the installation does not require, for example, ETA approval.

The concrete screw does not require a pre-tensioning torque to ensure the attachment, which means that when the screw has reached the substrate, all tightening should be avoided. The final tightening torque applied should not be greater than what is required to hold what is to be fixed in place. The tightening torque specified is the maximum tightening torque, not to be confused with other products that require a pre-tensioning torque (e.g. expander). The ECS concrete screw is fully hardened and therefore sensitive to skewed screwing. The drill hole should be 90 degrees to the substrate. The ECS concrete screw does not require blowing out the drill hole before installation, but the drill hole must be deep enough for the concrete screw to reach the correct setting depth despite any drilling dust remaining in the hole.
