A hinge pin for pivotally connecting a door to a frame comprises a pin body extending along a pivot axis between first and second ends, and a grease nipple portion extending longitudinally from the first end of the pin body. The pin body has an outer bearing shaped to enable the door to pivot relative to the frame about the pivot axis, a cross-bore extending radially inward from the outer bearing surface into the pin body, and a longitudinal bore extending into the pin body from the first end to the cross-bore. The longitudinal bore and the cross-bore together form a lubrication passageway. The pin body also has coupling portions for coupling the pin body to the door and the frame. The grease nipple portion is shaped to be coupled to a grease applicator for injecting grease into the lubrication passageway and is integrally formed with the pin body.
