This nut secures a bolted joint in a tillage machine assembly. It is a hex nut with a thread size of M8 and a hardness class of 8.8, meaning it is designed for high-strength fastening applications where the bolt is subjected to significant tensile loads. A nut of this class is typically used to clamp components such as tine carriers, disc scrapers, or frame brackets against the bolt's shoulder. If the nut loosens or is replaced with a lower-grade fastener, the joint can lose preload, leading to vibration-induced wear or component detachment. On reinstallation, ensure the nut is torqued to the specification for the mating bolt and that the threads are clean and free of debris.
