Coupling Nuts
Also known as extension nuts, these are commonly used to connect lengths of threaded rod and join threaded parts.
Low-Strength Steel
 |
Rated Grade 2 or lower, these are about half as strong as medium-strength steel coupling nuts. Use them with threaded rods that have a comparable strength rating to avoid stripping threads during installation.
Zinc-Plated Steel—A step up from plain steel, the zinc plating withstands occasional exposure to moisture.
Black-Oxide Steel—A dark, matte coating creates a finished look. Nuts offer minimal corrosion resistance, so they're best for dry environments.
Medium-Strength Steel
|
These Grade 5 or Class 8 nuts are about twice as strong as low-strength steel coupling nuts. Use them with threaded rods that have a comparable strength rating to avoid stripping threads during installation.
Zinc-Plated Steel—A step up from plain steel, the zinc plating withstands occasional exposure to moisture.
