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.

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.

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.

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.

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

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 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.

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

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.

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 to Japanese Industrial Standards, these nuts fasten most Japanese machinery and equipment without a washer.

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

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.

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

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

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

These 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.

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

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.

A smooth base on these metric nuts provides more contact with the mating surface than weld nuts with projections

Use these metric nuts in channels and tight spaces where round-base weld nuts won't fit.

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

These nuts have three mounting holes to accept screws and rivets for use with thin materials.

A hex- or square-shaped barrel allows these clip-on nuts to be gripped with a wrench to hold them in place when tightening a screw. They have multiple threads for more thread engagement than low-profile clip-on nuts.

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.

These rivet nuts are mildly corrosion resistant.

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.

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

With flexible teeth that slide smoothly over threads of any pitch, these push nuts can be used alone for light-duty applications or as a jam nut.

The most tamper-resistant nuts we offer, these have a hex head that breaks away upon tightening, leaving a non-removable cone. Install with a standard wrench.

Install in a cutout to create a secure joint between boards, butcher blocks, and countertops.

These include a barrel and a screw.

Add length to a binding barrel.

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.
