The depth of indentation of a following flank 56 on 52d, 52e becomes smaller with the increase in dimensions delta2, delta1 and the deformation resistance also becomes smaller, and the deformation resistances acting on both flanks 56, 58 become almost same. The depth of indentation of projections 52b, 52c is larger than that of the projections 52d, 52e and the amount of plastic deformation thus becomes larger. On the other hand, the amount of plastic deformation of the projections 52d, 52e whose deformation resistance is larger compared with the amount of plastic deformation becomes smaller due to the interference of padding, etc. and the deformation resistances can be bal anced. Consequently, the deformation resistance caused by the formation of a female screw does not locally concentrate.
