This steel rivet secures components within the cleaning system of the parent combine or forage harvester. It acts as a mechanical fastener, holding screens, deflectors, or other sheet-metal parts in position against vibration and material flow. A loose or missing rivet allows these components to shift, which can disrupt the cleaning airflow or allow crop material to bypass the intended path. This replacement part is manufactured to match the original’s shank diameter and head profile, so it seats correctly in the pre-drilled hole without requiring reaming. On installation, ensure the rivet is fully seated and the tail is formed to the correct shape for a tight, permanent joint.
