This rivet fastens sheet-metal panels and guards on the header and body of a grain combine or forage harvester. It is installed through aligned holes in two overlapping panels, where the shank fills the hole and the head bears against the outer surface. A loose or missing rivet allows panel vibration and can lead to fatigue cracking around adjacent fasteners. The original part matches the hole diameter and grip length of the factory assembly, so no reaming or shimming is needed during replacement.
