About 25% stronger than medium-strength steel nuts, these nuts are comparable in strength to class 10.9 bolts.

About half the strength of medium-strength steel nuts, these metric nuts are for light duty fastening applications.

These metric nuts are about 20% stronger than high strength steel nuts and are often used in heavy machinery.

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

These brass nuts resist rusting from water and have closely spaced threads to prevent loosening from vibration.

These metric nuts are resistant to salt water, electrically conductive, and nonmagnetic.

These nuts are half the height of standard hex nuts, and have closely spaced threads to prevent loosening from vibration. Half as strong as medium-strength steel nuts, they are often used for light-duty applications, such as fastening signs in place.

These nuts tighten when turned to the left; once fastened, they resist loosening from counterclockwise motion. Made of Grade 2 and Class 04 steel, these nuts can be used for fastening panels and other light duty fastening applications.

Made with fine-pitch threads, vibration is less likely to loosen these metric nuts than those with coarse-pitch threads since the threads sit closer together. Also called jam nuts, they are roughly half the height of standard hex nuts, so they’re good for applications with low clearance.

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.

Made from brass, these metric nuts are corrosion resistant in wet environments, electrically conductive, and nonmagnetic. About half the height of standard hex nuts, they are useful in low-clearance applications but have less tensile strength.

These Class 10 nuts are about 25% stronger than medium-strength steel extra-wide hex nuts.

Closely spaced metric threads prevent loosening from vibration. These Class 10 steel locknuts are 25% stronger than our medium-strength steel nylon-insert locknuts.

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 locknuts have good chemical resistance.

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

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

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.

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.

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

About half the strength and two-thirds the height of medium-strength steel square nuts, use these metric nuts in light duty, low-clearance applications.

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

These metric cap nuts have excellent resistance to chemicals and salt water.

Comparable in strength to Class 10.9 bolts, these nuts are about 25% stronger than medium-strength steel cap nuts.

Made from 18-8 stainless steel, these metric 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.

Choose these locknuts to fasten standard metric threads. They’re Class 8 steel, so they can be used in most fastening applications.

These metric coupling nuts have good chemical resistance.

You can weld these metric nuts to flat and uneven uncoated stainless steel surfaces for a strong permanent hold.

Teeth on the outside edge of these metric washers bite into the screw head and joint for a tight grip.

To keep 90° countersunk screws from loosening in vibration applications, the teeth on these washers bite further into the screw head and joint than standard external-tooth lock washers for a more secure hold.

These metric thumb screws have wings that provide more leverage than spade-head thumb screws for greater torque while tightening. A zinc plating provides corrosion resistance in wet environments.

With teeth along the inside, these retaining rings hold chamfered shafts inside the housing of your equipment.

Used in pairs or with another bearing retaining nut, these jam nuts—often called shaft nuts—hold bearings, bushings, pulleys, and gears in place on your threaded shaft or spindle.

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.

Secure setup clamps and fixtures to your machine table, or assemble heavy machines, such as engine mounts.

For quicker setups than a separate T-slot nut and stud, slide these bolts into T-slot tracks on machine tool tables.

Use these fittings in low-pressure flow applications. They have good corrosion resistance.

Pair these nuts with compression sleeves and high-pressure fittings. They withstand about twice as much pressure as nuts for standard compression fittings, so they’re good for hydraulic power applications.

Use these nuts with compression sleeves and fittings to create a strong seal on stainless steel tubing.

Create a strong seal on copper tubing when you couple these nuts with compression sleeves and fittings.
