CONCRETE SCREW EUSA4-HF, HEX HEAD WITH FLANGE, STAINLESS STEEL A4
-
ESSVE concrete screw EUSA4 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.
