Low-Strength Steel
 |  |
Rated Grade 2, Class 6, or lower, these nuts are about half as strong as medium-strength nuts. They are suitable for light duty fastening applications, such as securing access panels. Use them with screws that have a similar strength rating to avoid stripping threads during installation.
Steel—Best for dry environments since moisture will cause these nuts to rust.
