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.
Steel — Best for dry environments since moisture will cause these nuts to rust.
