Heavy-Profile Hex Nuts
About 10% wider and taller than standard-profile hex nuts, these handle heavier loads by distributing them over a larger area.
Extreme-Strength Steel
![]() |
These nuts are about 20% stronger than high-strength steel nuts. 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.
PTFE-Coated Steel—A slippery PTFE coating prevents these nuts from becoming stuck during installation. They resist rust in wet and outdoor environments, however they're not recommended for prolonged exposure since the coating can wear off.
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.
Zinc-Plated Steel—A step up from plain steel, the zinc plating withstands occasional exposure to moisture.
