These nuts are comparable in strength to Grade 9 bolts.

Also kown as heavy hex nuts, these nuts are about 10% wider and taller than standard hex nuts to distribute load over a large area.

About half the strength of medium-strength steel extra-wide hex nuts, use these nuts for light duty fastening applications, such as securing access panels.

These nuts have good chemical resistance.

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

These nuts have good chemical resistance.

Able to maintain their strength in high-pressure and high temperature environments, these nuts are used with ASTM A193 bolts to fasten pressure tanks, valves, and flanges.

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

These nuts are often used in conjunction with an extra-wide hex nut to fasten Grade 9 bolts in heavy machinery, such as earth-moving equipment.

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