About Hex Nuts
Choose a hex nut with the right profile, material, and strength for your application.
Hex Nuts
The most commonly used hex nuts, these are suitable for fastening most machinery and equipment.
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.
Steel—Best for dry environments since moisture will cause these nuts to rust.

Threaded Rods
Anchor, connect, or hang components in a wide variety of applications, from mounting I-beams to suspending light fixtures.
High-Strength Steel
![]() |
With a tensile strength of 150,000 psi, these rods are strong enough to stabilize steel frameworks and structural supports, such as I-beams. They are about 25% stronger than medium-strength steel rods. To avoid stripped threads during installation, make sure your nuts are also high-strength steel.
Steel—Best for dry environments since moisture will cause these rods to rust.
Medium-Strength Steel
![]() |
With tensile strengths from 110,000 psi to 125,000 psi, these rods are strong enough for most industrial applications, such as anchoring machinery and connecting pipe flanges. They are about twice as strong as low-strength steel rods. To avoid stripped threads during installation, make sure your nuts are also medium-strength steel.
