Abstract
A pull-out pin is adapted to couple first and second objects to each other. The pull-out pin is adapted to be removably and tightly inserted through a pin hole of the first object and into a pin hole of the second object. The pull-out pin includes spaced-apart first and second end surfaces, and an outer surrounding surface connected between the first and the second surfaces and surrounding a central axis. The outer surrounding surface has a recessed surface portion defining a vent groove extending from the first end surface in a direction toward the second end surface, and a helical groove extending helically about the central axis from the first end surface toward the second end surface, and intersecting the vent groove.
