SPRING NUT (KU-RG15847290)
Description:
The Spring Nut (RG158-47290) is a small OEM Kubota fastening nut with a spring action that helps secure components in place while allowing a bit of movement or tension — for example in panels, guards, linkage brackets, or accessory mounts. It combines a nut thread with a spring element so it stays in position during assembly and service and helps resist loosening from vibration.
Because it’s a small hardware part, it’s often used in maintenance and repair tasks where retaining other components securely is important. Keeping the correct spring nut in place helps prevent rattles and loosening over time.
