    The most commonly used hex nuts, these are suitable for fastening most machinery and equipment.
    High-Strength Steel
    Rated Grade 8, Grade C, or Class 10, these nuts are about 25% stronger than medium-strength steel nuts. They are commonly used to fasten components in valves, pumps, motors, and other high-stress applications. To avoid stripped threads during installation, make sure your screw has a comparable strength rating.
    Blue Dyed Steel—These metric-sized nuts have a distinctive blue color, so you can easily tell them apart from inch nuts.
