Abstract
A torque converter includes an impeller and a cover non-rotatably fixed to the impeller. The cover has opposing inner and outer surfaces and a through hole extending from the inner surface to the outer surface. A lug has a collar adjacent the outer surface, a shank extending from a first side of the collar, and a stem extending from a second side of the collar. The stem is disposed in the hole and attached to the cover by a connection.

A torque converter comprising:
- an impeller including a shell and impeller blades fixed to an inside surface of the shell;
- a turbine configured to fluidly couple with the impeller;
- a cover non-rotatably fixed to the impeller, the cover including opposing inner and outer surfaces and defining a plurality of circumferentially arranged through holes having sidewalls extending from the inner surface to the outer surface;
- and
- a plurality of lugs configured to connect the cover to a flex plate, each of the lugs including a shank and a stem, wherein the stems are disposed in corresponding ones of the holes such that the shanks extend from the outer surface of the cover, and the stems are attached to the cover by coalescence between the stems and the sidewalls.
