Choose a hex nut with the right profile, material, and strength for your application.
Heavy-Profile Hex Nuts for High-Pressure Applications
High-Strength Steel
 |
Rated Grade 7 or Grade 8, these nuts are about 25% stronger than medium-strength steel nuts. To avoid stripped threads during installation, make sure your screw has a comparable strength rating.
Zinc-Plated Steel—A step up from plain steel, the zinc plating withstands occasional exposure to moisture.
Black-Oxide Steel—Typically chosen for their appearance, these nuts have a dark, matte coating to create a finished look. They offer minimal corrosion resistance, so they're best for dry environments.
Steel—Best for dry environments since moisture will cause these nuts to rust.

Acme Lead Screws and Nuts
 |
Found in hand-powered clamps, vises, grates, doors, and work tables, lead screws and nuts have broad, square threads that are well suited for quick assembly, high clamping forces, and lifting and lowering heavy objects. To ensure compatibility, please select components that have the same thread direction, thread size, and number of thread starts.
Lead Screws—Right-Hand Thread
 |
Alloy Steel—Alloy steel components are harder and stronger than carbon steel components.
Travel Distance per Turn—Travel distance per turn, also known as screw lead, is the distance a nut or handle moves with one revolution of the lead screw.

Steel Heavy Hex Head Screw Kits for Metal Pipe Flanges
 |  |
Shown Installed |
All the hardware you need to join steel or cast iron pipe flanges. These kits come with screws and nuts in the right size and number to match your flange's bolt holes. With screw heads and nuts that are about 10% wider than standard, these kits handle heavier loads by distributing them over a larger area. The head also gives you six, flat contact points, so wrenches and sockets won't slip and round off the drive.
Screw length is measured from under the head. For a tight seal, you’ll also need a gasket between the flanges.
ASTM Grade L7—In addition to handling high heat, these screws stay strong in freezing temperatures without cracking. They're frequently used in industrial refrigeration systems, cold-storage facilities, and pipelines for oil and gas.

Threaded Rod and Hex Nut Kits for Pipe Flanges
 |
These kits include the rods and nuts you need to connect standard-size pipe flanges. Their heavy duty material and construction keep tanks, valves, and flanges tightly sealed under heavy pressure. With a 10% wider profile than standard hex nuts, these hex nuts spread force over a larger area and can handle extra torque during installation. The rods are fully threaded to distribute and absorb high levels of clamping force. To ensure your pipe flange connection is tight, add a pipe flange gasket to your installation. These rods and nuts meet a number of rigorous industry specifications for high-pressure performance, high-temperature performance, and dimensional requirements.
Medium-Strength Steel
 |
With a tensile strength of 125,000 psi, these rods are strong enough for most industrial applications, such as anchoring machinery and connecting pipe flanges. They are about twice as strong as low-strength steel rods.
Steel—Best for dry environments since moisture will cause these rods to rust.
Corrosion-Resistant PTFE-Coated Steel—A PTFE coating protects the steel from corrosion and pitting when exposed to chemicals, such as those found in cleaners and sanitizers. The coating is also slippery to thread on smoothly.
