This screw is a genuine Tecumseh replacement part for several different kinds of small engines, including lawn tractors, lawn mowers, snowblowers, woodchippers, and generators. A screw's function is to tightly join parts together through rotation of the screw. This prevents the materials from loosening and unfastening over time. A screw might be misplaced or lost the screw altogether, since it is a small object that can easily fall out of its place and disappear if loosened.
