The behaviour of bolts M10 made by cold forming, will be testing with bolts, which are heat treated after cold forming. Main different between this bolts is in material. As material will choose micro-alloyed steel 8Mn2Si. It is important for economicaly point of view. The manufacture by cold forming is cheaper than hot forming. The results of the research show show that new bolts should fulfil the requirements of ČSN EN 20898-1. The measure should evolve of statistics and support simulation of cold forming process by finally elements method -FEM
