About half the strength of medium-strength steel flange nuts, use these metric nuts in light duty fastening applications, such as securing access panels.

Also known as collar nuts, these metric nuts have a flange that distributes pressure across the surface, so you don't need a washer. Made of high-strength Class 10 steel, they’re about 25% stronger than medium-strength steel flange nuts.

These Grade 5 flange nuts are suitable for fastening most machinery and equipment.

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

These flange nuts have a black-oxide finish for mild corrosion resistance in dry environments.
