Choose a hex nut with the right profile, material, and strength for your application.
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.
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.

Hex Nuts
The most commonly used hex nuts, these are suitable for fastening most machinery and equipment.
Corrosion-Resistant Stainless Steel
 |
PTFE-Coated 18-8 Stainless Steel—A slippery PTFE coating prevents these nuts from becoming stuck during installation. The coating resists
rust in wet and outdoor environments and can handle occasional exposure to mild acids and chemicals without corroding.
