It is a basic screw which is recommended for fixing moving objects, structures, constructional elements to solid materials. For stable, high-solid joint, the material of our basic screw – both in terms of the shank and the nut – is a 8. quality carbon steel with extremely good strength indicators. The solid material must be at least C20/25 in the case of concrete in accordance with ENV 206:1990-03. In case of stone or other solid materials, it is important that it is not fissile. During the application of the basic screw, after selecting the basic screw suitable for the object to be fixed and the expected load, the next step is to prepare the bore. After cleaning the bore, the basic screw must be placed in the bore vertically, then the expanding cone tightens the sleeve to the bore wall through the pressure on the screw head with a hammer, thus the position of the basic screw becomes stable. As a last step, the object to be fixed is placed on the screw. The nut should be tightened with a torque wrench for the safe joint. For the mounting torques belonging to the basic screw diameters, please get information from the downloadable technical data sheet! Our basic screws have CE certification. It is also known as Through-bolt
