Threaded Rods

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

High-Strength Steel

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

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.

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

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.

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.

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

Corrosion-Resistant Hot-Dipped Galvanized Steel—Combines the strength of steel with the rust resistance of stainless steel. These rods are an economical alternative to 18-8 stainless steel in wet and outdoor environments, but they won't hold up to salt water and chemicals. Use with hot-dipped galvanized nuts.

Steel—Best for dry environments since moisture will cause these rods to rust.

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.

Super-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.
