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—The most common choice for areas with occasional exposure to moisture.

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.

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.

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.

Internally Threaded Ball Joint Rod Ends

Made of steel, these rod ends generally handle higher loads than stainless steel, aluminum, and nylon rod ends. They don’t come lubricated, so you’ll need to lubricate them during installation and on an ongoing basis.

Oversized Shank—Rod ends with an oversized shank have a shank that is one size larger than the ID to handle greater stress.

Zinc-Plated Carbon Steel—Zinc-plated steel rod ends provide moderate corrosion resistance.

Internally Threaded Lubrication-Free Ball Joint Rod Ends


Ball Joint Rod End

A carbon fiber-reinforced insert or PTFE liner reduces wear, handles shock loads, and eliminates the need for lubrication. Made of steel, these rod ends generally handle higher loads than stainless steel, aluminum, and nylon rod ends. All are zinc plated, so they resist corrosion for a short time before the finish is consumed and the steel is exposed.
