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.

More corrosion resistant than 18-8 stainless steel nuts, these nuts have excellent resistance to chemicals and salt water.

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