High-Strength Steel Threaded Rods

Grade 8 steel threaded rods are 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.
Low-Strength Steel Threaded Rods

About half the strength of medium-strength steel threaded rods, use these for light duty hanging, mounting, and fastening.

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.
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.

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.
