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

These metric nuts tighten when turned to the left; once fastened, they resist loosening from counterclockwise motion.

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

Half as thick as regular hex nuts, these nuts fit into spaces with low height clearances. They are about half as strong as medium-strength steel, and are often used for light duty applications, such as securing access panels.

Useful in low-clearance applications, these metric nuts are roughly half the height of standard hex nuts, but aren’t as strong. All are 18-8 stainless steel, which is nearly as strong as steel but won’t rust in outdoor, washdown, and other corrosive environments.

These metric nuts are made of 316 stainless steel and half as tall as regular hex nuts—use them around chemicals and salt water when space is limited.

Comparable in strength to Class 12.9 bolts.

A nylon insert keeps metric bolt threads from coming loose due to vibration, wear, and temperature swings. About 25% stronger than medium-strength steel locknuts, these nuts are made of high-strength, Class 10 steel.

Get a grip on metric bolts exposed to vibration, wear, and changes in temperature. These metric locknuts have a nylon insert that holds onto bolts without damaging their threads.

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

These metric locknuts have an irregularly shaped thread at the top of the nut that grips the bolt for a stronger hold than nylon-insert 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.

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.

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

These metric coupling nuts have good chemical resistance.

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

Cover exposed threads with these caps to help prevent bacteria growth in food processing areas and other sanitary environments.

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.

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

Precision cut threads make these metric ball screws approximately four times more accurate than standard ball screws. Use them when exact positioning is essential.

Install these threaded collars on a metric lead screw to separate and position components, or use them as an end stop to limit travel.

Often paired with spring lock washers to strengthen their hold, these retaining nuts—also known as shaft nuts—keep vibration from shifting bearings, bushings, pulleys, and gears on your threaded shaft or spindle.

Designed to slide into T-slot tracks on machine tool tables, use these nuts to secure clamps and workpieces.

Combine these setup studs with T-slot nuts, flanged nuts, setup clamps, or setup blocks to clamp and hold workpieces, vises, and other objects onto your fixturing table. Also known as double-ended studs, they have threads on both ends.
