These nuts are suitable for fastening most machinery and equipment.

These metric nuts meet JIS (Japanese Industrial Standard) B 1181.

Closely spaced metric threads prevent these nuts from loosening due to vibration. About 25% stronger than medium-strength steel nuts, these nuts are comparable in strength to Class 10.9 bolts.

These nuts come with a traceable lot number and a physical and chemical test report.

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

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

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

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

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

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

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

Comparable in strength to Grade 5 steel and as resistant to chemicals and salt water as 316 stainless steel.

Hardened for added strength, these nuts are more corrosion resistant to chemicals and salt water than 18-8 stainless steel nuts.

These nuts resist sticking during installation and are comparable in strength to Grade 5 steel.

One-third the weight of steel, these aluminum nuts are corrosion resistant in wet environments and nonmagnetic.

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

Glass-filled nylon nuts are stronger than nylon 6/6 nuts. They resist oil, grease, and solvents (except mineral acids).

These nuts have a high strength-to-weight ratio and resist acids and salt water.

Polypropylene nuts resist organic solvents and degreasing agents.

Polycarbonate nuts stand up to oil, grease, and detergents.

These metric nuts have a high strength-to-weight ratio and resist acids and salt water.

Ceramic nuts won't melt, seize, or become brittle—even at temperatures up to 3000° F.

More corrosion resistant than 400 nickel nuts, these nuts are often used in marine environments and chemical-processing plants.

Stronger than PTFE nuts and resistant to solvents, bases, and acids—including hydrochloric and nitric acid—these PVDF nuts are often used in chemical processing equipment.

PVC nuts resist acids, alkalies, salt solutions, and alcohol.

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.

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.

These nuts are about 25% stronger than medium-strength steel thin hex nuts. Available in inch thread sizes.

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 nuts have excellent chemical resistance and can be used in saltwater environments.

Plastic nuts are chemical resistant, nonconductive, and lightweight.

One-third the weight of steel, aluminum nuts resist corrosion in wet environments.

These nuts are comparable in strength to Grade 9 bolts.

Also kown as heavy hex nuts, these nuts are about 10% wider and taller than standard hex nuts to distribute load over a large area.

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

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

More corrosion resistant than 18-8 stainless steel nuts, these nuts can be used in saltwater environments.

Able to maintain their strength in high-pressure and high temperature environments, these nuts are used with ASTM A193 bolts to fasten pressure tanks, valves, and flanges.

These nuts have good chemical resistance.

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

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

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

Use these nuts for light duty fastening applications, such as securing access panels.

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

Known for their strength, steel coupling nuts are available with a corrosion-resistant finish.

These 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.

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

Comparable in strength to Grade 9 bolts, these coupling nuts are about 20% stronger than high-strength steel coupling nuts. Available in inch thread sizes.

Made from Grade 5 steel, these inch-sized coupling nuts are suitable for most applications.

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

Plastic coupling nuts are chemical resistant, nonconductive, and lightweight.
