CONCRETE SCREW ECS-C, COUNTERSUNK HEAD, BRIGHT ZINC PLATED
Area of usage
ESSVE ECS Concrete Screw is an affordable concrete screw for simpler applications where the assembly does not require e.g. ETA approval.
ECS is a hardened concrete screw that is pulled directly into a pre-drilled hole, without a plug. It has a so-called hi-Low thread That deliver good load values and Facilitates assembly. The concrete screw is made from hardened steel.
The surface treatment is electro zinc plated, which gives 15 years of resistance in corrosivity classification C1. Which corresponds to installation indoors in heated areas with dry air and insignificant amount of impurities. e.g. offices, shops, schools, hotels. According to SS-EN ISO 9223 and SS-EN ISO 12944-2.
When mounting, an impact screwdriver is recommended. See installation instructions.
The concrete screw does not require a preload torque to ensure the fixing, which means that when the screw has reached the surface, all tightening must be avoided. The final torque applied shall not be greater than that required to hold what is to be fixed in place. The tightening torque specified is the maximum torque, not to be confused with other products that require a preload operation.
The ECS concrete screw is through hardened and therefore sensitive to oblique mounting. The bore shall be 90 degrees to the substrate.
ESSVE ECS Concrete Screw has no requirement for blowing of borehole before installation, but the borehole must be deep enough to assemble the Concrete screw in along with the dust that is left behind. Otherwise, the screw will not be mounted to the right depth. ESSVE ECS Concrete Screw has no requirement for purging of borehole before installation, but the bore must be deep enough to assemble the Concrete screw in along with the dust that is left behind. Otherwise, the screw will not be mounted to the right depth.
