Abstract
A bolt is provided with a male thread, an end portion of which is of modified configuration, for acceptance in an element having a female thread of standard configuration. The modified portion of the male thread has a wedge ramp at the root thereof and a decreased pitch relative to the standard pitch of the thread on the female element which, in combination, results in optimum distribution of stress in the bolt as well as a prevailing torque relationship between the bolt and female element.
