Abstract (EN)
In this work different surface finished C1050 steel, 304 Stainless and Alüminium flanges has had been tightened by 8.8 grade M8, M10 ve M12 bolts in order to measure preload loses. During the experiments ultrasonic bolt monitor has been used. During the experiments first and last surface rougness of the flanges has been measured to calculate the amouth of plastic deformation due to the surface roughness lost. In the end of experiments, amounth of friction coefficient values, preload loses and plastical deformation values using to calculate bolt preloading is greater than the exact values. This causes overtighten and plasticaly deformed bolts.
