A clutch assembly for a torque converter, including: a cover; a piston plate including a hole; and a rivet in the hole. The rivet includes a rivet head. Prior to applying pressure to the rivet to fix the rivet to the piston plate, the rivet head is clamped between the piston plate and the cover. A clutch assembly for a torque converter, including: a cover; a piston plate with a hole; a leaf spring with a first end fixedly attached to the cover and a second end; and a rivet connecting the second end of the leaf spring to the piston plate. The rivet includes: a head disposed between the leaf spring second end and the cover; and a shaft in the piston plate hole. The piston plate or the cover is deflectable to clamp the rivet head between the cover and the piston plate before the shaft is expanded.
