Abstract
A threaded connection is subject in use after assembly to a load of specified magnitude in a selected direction along the thread axis. As so loaded, the basically constant pitch threads are uniformly stressed. The load faces of the threads on at least one of the members are defined, in the unstressed condition, to have a lead which varies from a constant lead by an amount which, at any given location along the threads, is equal to the amount of net relative deflection of the threaded members along the axis at such location in response to the application to the members of the load of specified magnitude. The design considerations pertinent to such a connection are set forth in the context of the presently preferred embodiment of the connection.
