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.
Steel—Best for dry environments since moisture will cause these rods to rust.
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
 |
Rated Grade 9 or Class 12, these nuts are about 20% stronger than high-strength steel nuts. They are strong enough to secure components in heavy machinery, such as bulldozers and excavators. 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.
Nylon-Insert Locknuts
Versatile yet economical, these are the most commonly used locknuts. The nylon insert grips the screw to prevent loosening from moderate vibration without damaging threads. However, the insert may become brittle if exposed to high temperatures. These locknuts are reusable a handful of times, but the holding power decreases with each use.
High-Strength Steel
 |
Rated Grade 8, Grade C, or Class 10, these locknuts are about 25% stronger than medium-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.
