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.

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.

Also known as extension nuts, use these to connect and extend threaded rods. Made from Grade 8 steel, they're about 25% stronger than medium-strength steel coupling nuts. A zinc plating provides corrosion resistance in wet environments.
