Often used to fasten parts in engines and turbines, these nuts are comparable in strength to Grade 8 steel.

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

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.

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

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.

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

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

50% taller than standard hex nuts, these metric nuts provide a larger gripping area for installation with a wrench.

Made from medium-strength steel with a nylon insert, these Class 8 metric locknuts are strong enough to use on most machinery and equipment that’s prone to vibration and temperature changes.

These locknuts have good chemical resistance.

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

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 and may be mildly magnetic.

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

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

These stainless steel locknuts have good chemical resistance and may be mildly magnetic.

A conical washer acts as a spring to add tension between the nut and the material surface for easy installation and mild vibration resistance. These metric locknuts have a smooth rim to resist scratching materials when tightened.

These locknuts have good chemical resistance.

These Grade 8 locknuts are about three times stronger than low-strength steel distorted-thread locknuts.

Strong enough for use with most machinery and equipment, these Class 8 metric locknuts have an irregularly shaped thread in the middle of the nut that grips bolts tighter than nylon-insert locknuts.

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

Stainless steel locknuts have excellent corrosion resistance in most environments.

Made from stainless steel, these metric flex-top locknuts resist chemicals and may be mildly magnetic.

Stainless steel locknuts have excellent corrosion resistance in most environments.

About two-thirds the height of standard steel-insert locknuts, use these locknuts in low-clearance applications or jam one against a hex nut to hold it in place.

These nuts are about 25% stronger than medium-strength steel flange locknuts.

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

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

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.

Made from 18-8 stainless steel, these flange nuts have good chemical resistance.

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

Made from Grade 8 steel, these nuts are about 25% stronger than medium-strength steel coupling nuts. Furnished in inch thread sizes.

These metric coupling nuts have good chemical resistance.

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

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

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

Stainless steel cap nuts have excellent corrosion resistance in most environments.

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

These cap nuts offer at least three-times the thread depth of standard cap nuts and are about twice the height.

The dome is open so these cap nuts can be used on bolts of any length.

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

A nylon insert grips threads to resist loosening.

Cap nuts cover and protect threads while providing a finished appearance.

Adapt threaded rods from inch to metric. These adapters connect two male-threaded fasteners, so you can change the gender of a mating part or increase or decrease its thread size. The hex-shaped body fits into the head of a standard wrench.

Increase or decrease metric thread size from one male-threaded part to another. Commonly used to connect two differently sized threaded rods, they have a hex-shaped body, so you can tighten them with a standard wrench.

In addition to joining male- and female-threaded parts, these adapters can increase or decrease metric thread sizes and change the thread pitch.

The through hole allows you to connect float rods to float valves.

Need to join two female-threaded parts, such as coupling nuts, with dissimilar inch thread sizes? Attach them to these adapters and tighten the exterior hex nut for a secure connection.
