Choose a hex nut with the right profile, material, and strength for your application.
Heavy-Profile Hex Nuts for High-Pressure Applications
High-Strength Steel
 |
Rated Grade 7 or Grade 8, these nuts are about 25% stronger than medium-strength steel nuts. To avoid stripped threads during installation, make sure your screw has a comparable strength rating.
Zinc-Plated Steel—A step up from plain steel, the zinc plating withstands occasional exposure to moisture.
Black-Oxide Steel—Typically chosen for their appearance, these nuts have a dark, matte coating to create a finished look. They offer minimal corrosion resistance, so they're best for dry environments.
Steel—Best for dry environments since moisture will cause these nuts to rust.
