Class 8 nuts are comparable in strength to Class 8.8 bolts and are suitable for fastening most machinery and equipment.

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 extra-wide hex nuts, use these nuts for light duty fastening applications, such as securing access panels.

Use these nuts for light duty fastening applications, such as securing access panels.

These nuts are about 25% stronger than medium-strength steel flange locknuts.

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.

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

A conical washer acts as a spring to add tension between the nut and the material surface for easy installation and mild vibration resistance. These metric locknuts have a smooth rim to resist scratching materials when tightened.

Threads at the top of these locknuts expand to grip the bolt on all sides for a stronger hold than distorted-thread locknuts.

Threads at the top of these metric locknuts expand to grip the bolt on all sides for a stronger hold than distorted-thread locknuts.

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

For light duty applications, choose these metric-sized coupling nuts.
