ESSVE concrete screw EUS2 A4 is a high-quality concrete screw designed for installation where high safety assembly is required, e.g. balcony railings, fall protection, steel plates, etc. It is CE-marked through an ETA (Option 1) and approved for use in both cracked and uncracked concrete. In addition, the ETA permits adjustment of the installation with shims.

Stainless steel A4 permits installation in aggressive environments, both in industry and near oceans. According to Eurocode guidelines (EN 1992-4), stainless steel fasteners should be used in outdoor environments and permanent moist indoor environments to obtain a minimum working life of 50 years.

The outer thread at the screw tip has welded carbide inserts that easily cuts thread in soft and hard concrete (C20/25 - C50/60).

When assembling, impact screwdrivers are recommended. The concrete screw does not require a preload torque to ensure the fixing (such as e.g. wedge anchors) The final torque applied should not be larger than what is required to mount the detail. Avoid over-tightening. Further information of the installation is included in the ETA.
