"The behaviour of bolts M10 made by cold forging without heat treatment was tested with heat treated bolts. Main different between this bolts is in material. For 4 operating production of bolts are going choose two diameters of workpieces. A ramming is going to choose so that it is going to discover dependence HV10=f(true deformation). This dependence is important for determination of inhomogeneity of deformation in bolts. The resusts of the research shoud show that bolts from steel 8Mn2Si should fulfil the requirements of \u010CSN EN 20898-1 norm."@en .
