Concrete Screw ECS-PW Ball Head With Washer Corrseal C4 7.5x200mm 300pcs Essve

Description

Essve Concrete Screw ECS is an affordable concrete screw for simpler applications where the installation does not require, for example, ETA approval. Is mainly intended for insulation, and can be used with advantage when necessary together with Roof Washer, 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, such as industry and coastal areas. An impact driver is recommended for installation. See installation instructions. 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 the object 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 must be 90 degrees to the substrate. The ECS concrete screw does not require the drill hole to be blown clean 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.
