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.

These flange locknuts have excellent resistance to chemicals and salt water. They have an irregularly shaped thread that grips the bolt for a stronger hold than nylon-insert flange locknuts.

Metric 316 stainless steel is also known as A4 stainless steel. These flange locknuts have excellent resistance to chemicals and salt water.

Made from 18-8 stainless steel, these flange locknuts have good chemical resistance and may be mildly magnetic

Stainless steel nuts have excellent corrosion resistance in most environments.

Weld these nuts to stainless steel surfaces.

Projections on the base concentrate the weld and provide room for heat to dissipate.

Create threads in hard-to-work areas—where you can’t reach the back of a workpiece, or material is too thin to be tapped.

These metric thumb nuts have good chemical resistance. The flange distributes pressure over a large area to reduce stress on your part.

Tighten these thumb nuts with a wrench for more torque while fastening.
