Extreme-Strength Steel Heavy Hex Nuts—Grade 2H
Because they’re about 10% wider and taller than standard hex nuts, these heavy hex nuts distribute the load over a large area. Grade 2H nuts are comparable in strength to Grade 9 bolts. They're about 20% stronger than high-strength steel nuts and are used in heavy machinery, such as earth-moving equipment.
Blue PTFE-coated steel nuts have a slippery surface to resist sticking during installation. They're resistant to chemicals and salt water.

Low-Strength Steel Heavy Hex Nuts
To distribute the load over a large area, these heavy hex nuts are about 10% wider and taller than standard hex nuts. They're about half the strength of medium-strength steel nuts and used for light duty fastening applications, such as securing access panels.
Zinc-plated steel nuts resist corrosion in wet environments.
Nuts that meet ASME B18.2.2 comply with standards for dimensions.
Nuts that meet SAE J995 comply with specifications for materials.

Medium-Strength Steel Threaded Rods—Grade B7
Grade B7, these threaded rods have a tensile strength about one and a half times stronger than low-strength steel rods. They meet the pressure and temperature requirements of ASTM A193 and are often used to secure pressure tanks, valves, and flanges.
