Abstract: A vehicle door hinge assembly according to this invention has a hinge bracket for mounting on each of a door and a body pillar of a vehicle. Each hinge bracket has a pair of spaced-apart legs wherein the pair of legs of one hinge bracket is received within and adjacent the pair of spaced-apart legs of the other bracket when the hinge brackets are hingedly mated together. The hinge brackets have aligned holes formed through their respective pairs of legs through which a hinge pin is received to hingedly mate the two hinge brackets together. The improvement comprises the hinge pin having a threaded tip or end and one of the legs of the outer hinge bracket having a nut affixed thereto in coaxial relation to the hole formed therein, or a the hole therein being threaded, and the threaded end of the hinge pin screwed therein when the hinge pin is inserted in the holes in the respective pairs of legs of the hinge brackets to hingedly mate the hinge brackets together.

Abstract: First and second stamping press lines have multiple stamping stations to serially stamp first and second parts into finished form and with bench marks reflective of the different stamping stations that also interrelate with one another to show if the stations are stamping to specifications. The marks on a part finished by the first line ideally match with the marks on a part finished by the second stamping line providing a visual indicator of quality so that the two separate parts can be permanently secured together with assurance of a quality assembly. Bench marks on separate parts that do not align or conform with one another identify stamping lines and stamping stations requiring adjustment or repair.
