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.
