Threaded Rods

Anchor, connect, or hang components in a wide variety of applications, from mounting I-beams to suspending light fixtures.

Medium-Strength Steel

Image of Product. Front orientation. Threaded Rods. Threaded Rods.

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.

Zinc-Yellow-Chromate-Plated Steel and Zinc-Plated Steel—The most common choice for areas with occasional exposure to moisture.

Black-Oxide Steel—Typically chosen for their appearance, these rods have a dark, matte coating that creates 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 rods to rust.

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.

Extreme-Strength Steel

Our strongest threaded rods have a tensile strength of 170,000 psi to hold up in your most demanding high-stress applications. They're about 20% stronger than high-strength steel rods. To avoid stripped threads during installation, make sure your nuts are also extreme-strength steel.

Low-Strength Steel

With a tensile strength of 50,000 psi or 60,000 psi, these rods are often used to suspend light fixtures, cable trays, and conduit from ceilings. They're about half the strength of medium-strength steel rods. To avoid stripped threads during installation, make sure your nuts are also low-strength steel.

Stainless Steel

More corrosion resistant than steel rods and comparable in strength to low-strength steel.

18-8 Stainless Steel—The choice for wet and outdoor environments, these rods resist rust. However, they won't hold up to the harsh chemicals that 316 stainless steel can.

Highly Corrosion-Resistant 316 Stainless Steel—Superior to 18-8 stainless steel, these rods won't degrade when exposed to harsh weather, salt water, and most chemicals.

Threaded on Both Ends Setup Studs

Known as setup studs, these studs withstand sideways forces better than fully threaded studs because they have a strong unthreaded middle. The unthreaded middle also makes more contact with unthreaded holes, creating better alignment than a fully threaded stud.

Metric Precision Lead Screws and Nuts

Pair with a motor in automated motion and positioning applications. A tight thread fit allows these lead screws and nuts to make accurate, repeatable starts and stops. Also known as single-start and self-locking lead screws and nuts, they have a single thread that runs the length of the screw. The nut travels only when the screw turns, so your system won’t unexpectedly move when the lead screw is at rest. To ensure compatibility, select components that have the same thread direction, size, and number of thread starts.

Lead Screws—Right-Hand Thread

1018 Low-Carbon Steel—Carbon steel lead screws and flanges have good machinability.

Travel Distance per Turn—Travel distance per turn, also known as screw lead, is the distance a nut moves with one revolution of the lead screw.
