In this paper, the deformation mode of high strength hexagon socket head cap bolts is analyzed and the strain expression of metal flow in the corners is proposed. Through the experimental research of high strength materials such as 35CrMoA, the rupture limit of materials is deduced. The research results can guide the high strength polygonal cavity Cold forging production of parts and axisymmetric parts.
