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.

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

Made from Grade 2 steel, these nuts should be used for light duty fastening applications, such as securing access panels.

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

A flange distributes the load over a large area and reduces stress where the nut meets the material surface.

Knurls provide a slip-resistant surface for controlled adjustment.

Use these thumb nuts in low-clearance applications or jam one against another nut to hold it in place.
