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.

About 10% wider and taller than standard hex nuts, these heavy nuts distribute the load over a large area. Medium-strength steel nuts are suitable for fastening most machinery and equipment.

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.

These nuts have good chemical resistance. Considered heavy hex nuts, they are about 10% wider and taller than standard hex nuts and distribute the load over a large area.

Brass nuts are resistant to corrosion in wet environments and electrically conductive. These nuts are considered heavy hex nuts because they are about 10% wider and taller than standard hex nuts and distribute the load over a large area.

Made from 400 nickel—also known as Monel—these nuts are often used on valves, pumps, and shafts because they resist salt water and caustic chemicals. They’re considered heavy hex nuts because they’re about 10% wider and taller than standard hex nuts and distribute the load over a large area.

More corrosion resistant than 18-8 stainless steel nuts, these nuts have excellent resistance to chemicals and salt water. They're able to maintain their strength in high-pressure and high-temperature environments and are used with ASTM A193 bolts to fasten pressure tanks, valves, and flanges. Considered heavy hex nuts, they are about 10% wider and taller than standard hex nuts and distribute the load over a large area.

These nuts are designed to secure ASTM A325 bolts in structural joints. About 10% wider and taller than standard hex nuts, these heavy hex nuts distribute the load over a large area.

These metric nuts are about 20% stronger than high strength steel nuts and are often used in heavy machinery.

Use these nuts for light duty fastening applications, such as securing access panels.

Brass nuts are resistant to corrosion in wet environments and electrically conductive.
