Abstract��Formed thread on connecting rod of fracture splitting is the industry��s advanced technology, but the standards of quality inspection and evaluation parameters are not very clear. The formation mechanism and extrusion process of formed thread were amply introduced on C70S6 fractured connecting rod as an example, and the advantages as well as main influence factors were summarized. At the same time the quality inspection and evaluation parameters of formed thread on fractured connecting rod were proposed. The parameters such as height percentage of thread, thread surface hardness, thread roughness and thread accuracy are especially important for the quality inspection and evaluation, and these parameters have been applied on formed thread of fractured connecting rod in production practice.
