Medium-Strength Steel Threaded Rods—Grade B7
Grade B7, these threaded rods have a tensile strength about one and a half times stronger than low-strength steel rods. They meet the pressure and temperature requirements of ASTM A193 and are often used to secure pressure tanks, valves, and flanges.
Zinc yellow-chromate plated steel threaded rods resist corrosion in wet environments.

High-Strength Steel Threaded Rods
Comparable to Grade 8 steel, these threaded rods have a tensile strength of 150,000 psi, making them about 25% stronger than medium-strength steel rods.
Zinc yellow-chromate plated steel threaded rods resist corrosion in wet environments.

Low-Strength Steel Threaded Rods
About half the strength of medium-strength steel threaded rods, use these for light duty hanging, mounting, and fastening.
Zinc-plated steel threaded rods are corrosion resistant in wet environments.

Low-Strength Steel Coupling Nuts
Also known as extension nuts, use these to connect and extend threaded rods. They're about half the strength of medium-strength steel coupling nuts for use in light duty fastening applications.
Zinc-plated steel coupling nuts resist corrosion in wet environments.
