Metric Left-Hand Threaded Medium-Strength Steel Hex Nuts

These metric nuts tighten when turned to the left; once fastened, they resist loosening from counterclockwise motion. They are suitable for fastening most machinery and equipment. A zinc plating provides corrosion resistance in wet environments.
Class 8 nuts are comparable in strength to Class 8.8 bolts.
