Hex Nuts

The most commonly used hex nuts, these are suitable for fastening most machinery and equipment.

Medium-Strength Steel

These Grade 5 or Class 8 nuts are your go-to for fastening most machinery and equipment. 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.

Zinc-Yellow-Chromate-Plated Steel—With a more durable finish than clear zinc plating, these nuts are suitable for most wet and outdoor environments. However, they won't hold up to the harsh chemicals that stainless steel can.

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.

Black Corrosion-Resistant-Coated Steel—Combines a finished appearance with the rust resistance of stainless steel. The coating has been tested to extreme standards, including 1,000 hours of salt spray resistance, to hold up in wet and outdoor environments. Also known as black luster.

Steel—Best for dry environments since moisture will cause these nuts to rust.

High-Strength Steel

Rated Grade 8, Grade C, or Class 10, these nuts are about 25% stronger than medium-strength steel nuts. They are commonly used to fasten components in valves, pumps, motors, and other high-stress applications. 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.

Zinc-Flake-Coated Steel—The most durable zinc coating, zinc flake is a multilayer finish that resists wear for long-term rust protection. Similar to zinc yellow-chromate, it won't hold up to harsh chemicals like stainless steel can.

Steel—Best for dry environments since moisture will cause these nuts to rust.

Blue Dyed Steel—These metric-sized nuts have a distinctive blue color, so you can easily tell them apart from inch nuts.

High-Strength Steel with Material Certificate

Nuts include a report with a traceable lot number and a description of their chemical and physical properties. Rated Grade 8, Grade C, or Class 10, these nuts are about 25% stronger than medium-strength steel nuts. They are commonly used to fasten components in valves, pumps, motors, and other high-stress applications. To avoid stripped threads during installation, make sure your screw has a comparable strength rating.

Low-Strength Steel

Rated Grade 2, Class 6, or lower, these nuts are about half as strong as medium-strength nuts. They are suitable for light duty fastening applications, such as securing access panels. Use them with screws that have a similar strength rating to avoid stripping threads during installation.

Zinc-Plated Steel—A step up from plain steel, the zinc plating withstands occasional exposure to moisture.

Hot-Dipped Galvanized Steel—Combines the strength of steel with the rust resistance of stainless steel. These nuts are an economical alternative to 18-8 stainless steel in wet and outdoor environments, but they won't hold up to salt water and chemicals. The galvanized finish is thicker than other types of coatings, so the threads may be more likely to stick during installation. Use with other hot-dipped galvanized fasteners.

Steel—Best for dry environments since moisture will cause these nuts to rust.

Corrosion-Resistant Stainless Steel

18-8 Stainless Steel—The choice for wet and outdoor environments, these nuts resist rust. However, they won't hold up to the harsh chemicals that 316 stainless steel can.

Black-Oxide 18-8 Stainless Steel—Typically chosen for their appearance, these nuts have a dark, matte coating to create a finished look. They resist rust in wet and outdoor environments, but won't hold up to the harsh chemicals that 316 stainless steel can.

PTFE-Coated 18-8 Stainless Steel—A slippery PTFE coating prevents these nuts from becoming stuck during installation. The coating resists rust in wet and outdoor environments and can handle occasional exposure to mild acids and chemicals without corroding.

Super-Corrosion-Resistant 316 Stainless Steel—Superior to 18-8 stainless steel, these nuts won't degrade when exposed to harsh weather, salt water, and most chemicals.

Super-Corrosion-Resistant Black-Oxide 316 Stainless Steel—Combines a finished appearance with the rust resistance of 316 stainless steel. Even if the coating wears off, these nuts will hold up in just about any environment, including salt water and most chemicals.

High-Strength 17-4 PH Stainless Steel—The strongest stainless steel nuts we offer, these are comparable in strength to Grade 8 steel. Use them in high-stress applications, such as fastening structural parts and pump components. They won’t rust in wet and outdoor environments, but they can’t handle the harsh chemicals and acids that 316 stainless steel can.

Super-Corrosion-Resistant High-Strength Bumax 88 Stainless Steel—Comparable in strength to Grade 5 steel and as corrosion resistant as 316 stainless steel. These nuts are commonly used in demanding environments, such as marine and chemical processing applications.

Seize-Resistant High-Strength 410 Stainless Steel—Resists sticking during installation and is comparable in strength to Grade 5 steel. These nuts are not as corrosion resistant as 18-8 stainless steel, so they're best for environments that experience occasional moisture.

High-Temperature High-Strength A286 Stainless Steel—Stronger than 316 stainless steel and withstands higher temperatures. These nuts resist corrosion from chemicals, such as bleach and chlorine, but they won't hold up to salt water as well as 316 stainless steel.

Ultra-Corrosion-Resistant Alloy 20 Stainless Steel—The most corrosion-resistant stainless steel nuts we offer, these hold up in just about any environment. They won't pit or weaken when exposed to salt water and harsh chemicals, such as sulfuric acid. Also known as Carpenter 20.

Lightweight Aluminum

6061 Aluminum—One-third the weight of steel, these nuts are commonly used in robotics, automation, and other applications that have weight limitations. They're an alternative to stainless steel for rust resistance but are not as strong.

Black Corrosion-Resistant-Coated 6061 Aluminum—Offers better rust resistance than plain aluminum. Also known as black luster, the coating creates a finished appearance and has been tested to extreme standards, including 1,000 hours of salt spray resistance, to hold up in wet and outdoor environments. One-third the weight of steel, these nuts are suitable for robotics, automation, and other applications that have weight limitations.

Lightweight Corrosion-Resistant Titanium

Grade 2 Titanium—The best of both worlds, these nuts are lightweight like aluminum and as corrosion resistant as 316 stainless steel. Because Grade 2 titanium is 99% pure, it's even more corrosion resistant than other common titanium grades, such as Grades 5 and 9. These nuts are ideal for use in chemical-processing and water-treatment facilities since they stand up to strong acids and other harsh chemicals.

Corrosion-Resistant Nickel

400 Nickel—Also known as Monel, 400 nickel is an economical alternative to titanium. These nuts are just as corrosion resistant to stand up to salt water and strong acids. Stronger than C276 nickel nuts, they are commonly used to fasten gauges and other components on valves, pumps, and shafts.

C276 Nickel—Also known as Hastelloy, these nuts have the best chemical resistance of all the metal nuts we offer. They resist pitting and cracking, even when exposed to the harshest substances, such as acids and sulfides. However, they aren't as strong as 400 nickel nuts.

Brass

Brass—Conductive and nonmagnetic, brass nuts are commonly used to secure electrical equipment, such as circuit board assemblies and mounting brackets, inside enclosures. They're also softer than most metals, so they won't damage other fastening components.

Nickel-Plated Brass—The nickel plating offers better corrosion resistance than plain brass to stand up to solvents, salt water, and chemicals. The plating can wear off over time, so these nuts are not recommended for applications that experience a lot of friction or wear.

Plastic

Nylon 6/6— The most common plastic nuts, these are good for general purpose fastening. They are slippery and abrasion resistant, so they thread on smoothly and stand up to daily wear and tear. Nylon will swell and weaken when exposed to moisture, so these nuts are best for dry environments.

High-Strength Glass-Filled Nylon—Glass fibers embedded in the nylon give these nuts better strength than nylon 6/6. They can also handle higher temperatures without losing strength.

Moisture-Resistant Acetal—The best plastic for damp and wet environments, these nuts won't swell or lose their strength if exposed to moisture. They also resist wear and scratches better than nylon nuts.

Clear Impact-Resistant Polycarbonate—Our most impact-resistant plastic nuts, these withstand bumps and vibration without cracking or denting. They are also clear to be less noticeable in your assembly.

Acid-Resistant PVC—Connect sensors, fittings, and other equipment in chemical-processing lines. These nuts won't degrade when exposed to harsh acids, alkalis, and alcohols.

High-Temperature Chemical-Resistant PTFE—The most chemical-resistant plastic nuts we offer, these stand up to the widest range of harsh acids, bases, solvents, and corrosive cleaners. They also keep their shape and strength at higher temperatures than most plastics.

Mil. Spec. Hex Nuts

These nuts are manufactured and tested to strict U.S. military standards for material and construction.

Medium-Strength Steel

Image of Product. Front orientation. Hex Nuts. Mil. Spec. Hex Nuts.

These Grade 5 or Class 8 nuts are your go-to for fastening most machinery and equipment. To avoid stripped threads during installation, make sure your screw has a comparable strength rating.

Cadmium Yellow-Chromate-Plated Steel— The plating creates a barrier against rust, so these nuts are suitable for most wet and outdoor environments. They also thread on smoothly without sticking.
