Key Information

This nut is a high-volume, standard hardware component used in critical structural joints, bucket tooth, bucket linkage assemblies, and chassis mountings. Because it is a standardized industrial part (GB6170), it is designed for high-tensile strength applications where consistent clamping force is required to prevent loosening under the extreme vibrations characteristic of construction machinery.
