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.

They're about 25% stronger than medium-strength steel flange locknuts and comparable in strength to Class 10.9 bolts.

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

These flange locknuts have excellent resistance to chemicals and salt water.

Made from brass, these flange locknuts are corrosion resistant in wet environments, electrically conductive, and nonmagnetic. They’re easy to install and resist mild vibration since serrations grip the material surface instead of the threads

Grip metric bolts more securely than nylon-insert flange locknuts—the irregularly shaped threads on these locknuts hold extra tight. They resist vibration and sudden shocks, even after multiple uses.

Choose these flange locknuts for their adherence to strict military standards for material and construction.

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.

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.

Made to Japanese Industrial Standards, these nuts fasten most Japanese machinery and equipment without a washer.

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

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.

Fiberglass flange nuts are chemical resistant, nonconductive, and lightweight.

Stainless steel nuts have excellent corrosion resistance in most environments.

Stainless steel nuts have excellent corrosion resistance in most environments.

A smooth base on these metric nuts provides more contact with the mating surface than weld nuts with projections

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

Use these metric nuts in channels and tight spaces where round-base weld nuts won't fit.

A smooth base provides more contact with the mating surface than weld nuts with projections.

Weld these nuts to uncoated steel surfaces.

These nuts have three mounting holes to accept screws and rivets for use with thin materials.

Stainless steel adhesive-mount nuts have excellent corrosion resistance in most environments.

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.

These metric thumb nuts are corrosion resistant in wet environments, electrically conductive, and nonmagnetic. The flange distributes pressure over a large area to reduce stress on your part.

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

Multiple thread channels (also known as thread starts) create faster linear travel than lead screws with a single thread start.

Also known as single-start and self-locking lead screws and nuts, these have a single thread that runs the length of the screw. The nut travels only when the screw turns, so your system won't unexpectedly move when the lead screw is at rest.

Combine with an externally threaded acme nut to create a custom flange nut.

These metric lead screws and nuts have broad, square threads that are well suited for quick assembly, high clamping forces, and lifting and lowering heavy objects. They're commonly found in hand-powered clamps, vises, grates, doors, and work tables.

Keep your ball screw spinning without the ball nut damaging your system. When the ball nut reaches the stop pin at either end of the ball screw, it disengages and begins to idle.

Also known as single-start ball screws and nuts, these have a single thread that runs the length of the screw. They operate with more torque than fast-travel ball screws and nuts.
