CONCRETE SCREW, EUS-HF HEX HEAD WITH FLANGE, RUSPERT
-
ESSVE concrete screw EUS 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.
-
The screw has a strong induction hardened tip that easily cuts thread in soft and hard concrete (C20/25 - C50/60). The body of the screw is more ductile to accommodate for installations that are slightly non-perpendicular. The Hi-Low thread provides very good load values and facilitates the assembly.
The Ruspert surface treatment gives a minimum of 15 years lifetime in corrosivity category C3. Which corresponds to installation in outdoor areas with moderate amount of air pollutants, such as urban areas and light industrialized areas according to ISO 9223. According to Eurocode-guidelines (EN 1992-4) stainless steel concrete screws should be used in outdoor and permanently damp indoor environments to obtain a minimum 50 year lifetime.
-
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.
