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.

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

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

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

About half the strength of medium-strength steel coupling nuts, these nuts are for light duty fastening applications.

Known for their strength, these steel cap nuts have a black-oxide finish to resist corrosion in dry environments.

These nuts can be tightened with a wrench once positioned by hand.

These nuts should be used for light duty fastening applications, such as securing access panels.
