High-Profile Hex Nuts
Slightly taller than standard-profile hex nuts, these have a larger gripping area so your wrench or socket won't slip off as you tighten them. They're often used in vehicles and machinery where fasteners can be difficult to reach.

High-Strength Steel
 |
Rated Grade 8, Grade C, or Class 10, these nuts are about 25% stronger than medium-strength steel nuts. They are commonly used to fasten components in valves, pumps, motors, and other high-stress applications. To avoid stripped threads during installation, make sure your screw has a comparable strength rating.
Material Certificate—Nuts include a report with a traceable lot number and a description of their chemical and physical properties.
Steel—Best for dry environments since moisture will cause these nuts to rust.
