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

    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.

    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.

    Coupling Nuts

    Image of Product. Front orientation. Coupling Nuts. Coupling Nuts.
    Also known as extension nuts, these are commonly used to connect lengths of threaded rod and join threaded parts.
    Low-Strength Steel
    Rated Grade 2 or lower, these are about half as strong as medium-strength steel coupling nuts. Use them with threaded rods that have a comparable strength rating to avoid stripping threads during installation.
    Zinc-Plated Steel—A step up from plain steel, the zinc plating withstands occasional exposure to moisture.
    Hot-Dipped Galvanized Steel—Combines the strength of steel with the rust resistance of stainless steel. These nuts 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 other hot-dipped galvanized fasteners to ensure the threads mate tightly.

    Threaded Rod and Hex Nut Kits for Pipe Flanges

    Image of ProductInUse. Front orientation. Threaded Rods. Threaded Rod and Hex Nut Kits for Pipe Flanges.
    These kits include the rods and nuts you need to connect standard-size pipe flanges. Their heavy duty material and construction keep tanks, valves, and flanges tightly sealed under heavy pressure. With a 10% wider profile than standard hex nuts, these hex nuts spread force over a larger area and can handle extra torque during installation. The rods are fully threaded to distribute and absorb high levels of clamping force. To ensure your pipe flange connection is tight, add a pipe flange gasket to your installation. These rods and nuts meet a number of rigorous industry specifications for high-pressure performance, high-temperature performance, and dimensional requirements.
    Medium-Strength Steel

    With a tensile strength of 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.
    Corrosion-Resistant PTFE-Coated Steel—A PTFE coating protects the steel from corrosion and pitting when exposed to chemicals, such as those found in cleaners and sanitizers. The coating is also slippery to thread on smoothly.
