This screw is used to fasten façades in place. Insulation thicknesses of 80 – 300 mm can be handled easily with the EiSYS-H screw from Eurotec.The EiSYS-H screw is fitted with a freely rotating adjustment sleeve/head that allows the space between the brickwork and the substructure to be tailored to your needs. A hexagonal bit is supplied as an accessory. This is used to screw the screw into the subsurface, as well as to adjust the substructure with the adjustment head.This is how it‘s done!The principle is as ingenious as it is simple.Once the insulation is attached to the exterior wall, the counter batten is pilot-drilled to a diameter of 13 mm in accordance with the system. A hole of 10 mm diameter is then drilled within this hole through the insulation and into the subsurface to create the hole for the plug. The plug is attached to the adjusting screw and the two are then inserted into the prepared drill hole through the counter batten and the insulation.The EiSYS-2 façade/adjusting screw is screwed in completely in position 1 using the hexagonal bit until the adjustment head also lies within the counter batten. Now, the screw is simply pulled out to position 2 using the hexagonal bit and the spacing between the brickwork and the counter batten is adjusted.
