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, they meet the pressure and temperature requirements of ASTM A193 and are often used to secure pressure tanks, valves, and flanges.
For technical drawings and 3-D models, click on a part number.
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.

18-8 Stainless Steel Threaded Rods
18-8 stainless steel threaded rods have good chemical resistance and may be mildly magnetic.
For technical drawings and 3-D models, click on a part number.
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.
For technical drawings and 3-D models, click on a part number.
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.
Black-oxide steel coupling nuts have a dark surface color and are mildly corrosion resistant in dry environments.
