Threaded Rods
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.
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.
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.
