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.
For technical drawings and 3-D models, click on a part number.
Medium-Strength Steel Threaded Rods—Grade B7

These Grade B7 threaded rods 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.
Medium-Strength Steel Threaded Rods—Grade B16

Grade B16 threaded rods maintain their strength at higher temperatures than Grade B7 threaded rods. They meet 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.
Hot-dipped galvanized steel coupling nuts have a thick coating for better corrosion resistance than zinc-plated steel nuts. They must be used with other hot-dipped galvanized fasteners.

Medium-Strength Steel Coupling Nuts—Grade 5

Also known as extension nuts, use these to connect and extend threaded rods.
Zinc-plated steel coupling nuts resist corrosion in wet environments.

Steel Extra-Long Coupling Nuts

Also known as sleeve nuts, these are at least twice the length of standard coupling nuts to provide more room to connect and extend long lengths of threaded rods.
Zinc-plated steel nuts resist corrosion in wet environments.
