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.

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.

Left-Hand Threaded Medium-Strength Steel Threaded Rods—Grade B7
Tighten these threaded rods by turning them to the left; once fastened, they resist loosening from counterclockwise motion. Made from Grade B7 steel, their tensile strength is one and a half times higher than low-strength steel rods. They also meet the pressure and temperature requirements of ASTM A193, so they are often used to secure pressure tanks, valves, and flanges.

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.
Hot-dipped galvanized steel threaded rods have a thick coating for better corrosion resistance than zinc-plated steel threaded rods. They must be used with other hot-dipped galvanized fasteners.

Super-Corrosion-Resistant 316 Stainless Steel Threaded Rods
More corrosion resistant than 18-8 and 410 stainless steel threaded rods, these 316 stainless steel rods have excellent resistance to chemicals and salt water and may be mildly magnetic.
