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

These nuts tighten when turned to the left; once fastened, they resist loosening from counterclockwise motion. They’re Grade 5 steel, so you can used these inch-sized nuts for most fastening applications.

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

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

Also known as small-pattern hex nuts, these are about 20% narrower than standard hex nuts for use in tight spaces where standard hex nuts won't fit.

These nuts are often used in conjunction with an extra-wide hex nut to fasten Grade 9 bolts in heavy machinery, such as earth-moving equipment.

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

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.

Made from low-strength steel, these locknuts should be used for light duty fastening applications, such as securing.access panels.

With a shorter hex height than standard DIN 985 locknuts, these nylon-insert locknuts meet international ISO 10511 dimensional standards and are easy to install in tight spaces.

Grade 5 locknuts are suitable for fastening most machinery and equipment when used in conjunction with a standard hex nut.

Known for their strength, these locknuts are zinc-plated to resist corrosion in wet environments.

These metric locknuts have a free-spinning tooth lock washer that grips the material surface instead of threads for easy installation and mild vibration resistance.

These locknuts have a curved washer that acts as a spring for easy installation and mild vibration resistance. The smooth rim makes them less likely to scratch materials when tightened than locknuts with a tooth lock washer.

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.

About half the strength of medium-strength steel locknuts, these are for light duty fastening applications, such as securing access panels.

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.

Secure these metric nuts by inserting a cotter pin or safety wire through the slots and a drilled hole in your bolt for mild loosening resistance. Often referred to as castle nuts.

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.

Grade F nuts are comparable in strength to Grade 5 bolts.

Made from Grade 8 steel, these nuts are about 25% stronger than medium-strength steel flange nuts.

These metric nuts meet JIS (Japanese Industrial Standard) B 1190.

These Grade 5 flange nuts are suitable for fastening most machinery and equipment.

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

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

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

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

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

These metric nuts are about half the strength of medium-strength steel cap nuts. Use them in light duty fastening applications, such as securing access panels.

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

A nylon insert on these metric nuts prevents vibration from loosening them, and a domed head protects the threads at the end of the bolt from damage and debris.

These metric wing nuts provide more leverage for greater torque while tightening than knurled-head thumb nuts.

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.

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.

Threads float inside the retainer so you can install a bolt at a slight angle to align with off center parts.

These adhesive-mount nuts have a zinc plating for corrosion resistance in wet environments.

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

These Grade 5 square nuts are suitable for fastening most machinery and equipment.

Press these metric nuts into a drilled or punched hole with an arbor press or similar pressure tool.

These press-fit nuts have a nylon insert that grips threads to resist loosening.

About twice as strong as aluminum rivet nuts, these rivet nuts are zinc plated for mild corrosion resistance.

Threads float inside the nut so you can install a screw at a slight angle to align with off-center parts. They’re also known as Riv-Float nuts.

These panel nuts are knurled to provide a secure grip for tightening and loosening by hand.

Use these light-duty clip-on nuts in low-clearance applications.

The S-style design provides more strength than other no-slip clip-on nuts.

Slide these nuts on the edge of a panel and position them by hand. Also known as G-style clip-on nuts.

Tri-groove nuts are narrower than sloped and drilled spanner nuts to fit in tight spaces. Install with a tri-groove socket bit and either a drive handle or an open-end wrench.

Attach these metric slip-on nuts at any point on a threaded rod for quick installation.
