For a secure hold where chemicals are a concern, these stainless steel locknuts have a spring that creates tension when tightened. Also known as Fuji locknuts.

Strong enough for use in most machinery and equipment, these medium-strength metric nuts have serrations on the underside of the flange. The serrations prevent the nuts from loosening in applications with mild vibration.

Metric 18-8 stainless steel is also known as A2 stainless steel. These flange locknuts have good chemical resistance and may be mildly magnetic.

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.

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.

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

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

These metric cap nuts have good chemical resistance and may be mildly magnetic.

These metric nuts are about half the strength of medium-strength steel cap nuts. Use them in light duty fastening applications, such as securing access panels.

These metric nylon 6/6 cap nuts are chemical resistant, nonconductive, and lightweight.

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

These metric-sized coupling nuts are Class 10 steel, so they’re about 25% stronger than medium-strength steel coupling nuts.

More corrosion resistant than 18-8 stainless steel coupling nuts, these metric nuts have excellent resistance to chemicals and salt water.

Brass coupling nuts are corrosion resistant in wet environments and electrically conductive.

A smooth rounded body provides a finished look.

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

Two-thirds the height of typical square nuts and made of stainless steel, these metric nuts are designed for use in low-clearance applications in humid, damp, and washdown environments.

Press these metric nuts into a drilled or punched hole with an arbor press or similar pressure tool.

A flat hex head sits flush against the material surface for use in low-clearance applications.

Stainless steel press-fit nuts have excellent corrosion resistance in most environments.

These press-fit nuts are tin plated to resist corrosion from chemicals and salt water.

These metric wing nuts provide more leverage for greater torque while tightening than knurled-head thumb nuts.

Made from 316 stainless steel, these metric wing nuts have excellent chemical resistance and can be used in saltwater environments.

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

Made from 18-8 stainless steel, these metric thumb nuts have good chemical resistance and may be mildly magnetic.

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