    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.
    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.

    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.

    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.
