Made from Grade 8 steel, these nuts are about 25% stronger than medium-strength steel flange nuts.

These metric nuts meet JIS (Japanese Industrial Standard) B1190.

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

No need for a washer—these metric medium-strength steel nuts have a flange that distributes pressure across its surface the way a washer does. Made of medium-strength, Class 8 steel, they’re suitable for fastening most machinery and equipment.

Skip the washer—these metric stainless steel nuts have a flange that does the same job, spreading pressure across its surface for a strong hold.

The nut head rotates while the flange remains stationary to prevent scratching the material surface as you tighten the nut.
