ABSTRACT:
A tubular piston pin for an internal combustion engine being of lightweight and high strength design with a cylindrical exterior surface and a double hourglass shaped aperture defined by thin-walled end portions; a thin-walled intermediate portion and two thicker-walled portions therebetween. A method for easy and inexpensive piston pin manufacture includes: the formation of half pins by molding a metal slug between two dies each having tapered end portions, punching out a midportion or intermediate web or wall to form an aperture therethrough with a generally hourglass shape, and aligning and joining two half pins axially together to form a piston pin with the double hourglass shaped interior aperture.
