Made from Grade 5 steel, these inch-sized locknuts are suitable for fastening most machinery and equipment.

Choose these locknuts for their adherence to strict military standards for material and construction. They’re low-strength steel, so they should be used for fastening panels and other light duty fastening applications.

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

These locknuts are about half the height of standard nylon-insert locknuts. Use them in light duty low clearance applications or jam one against a hex nut to hold it in place.

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

Also known as Keps and K Lock nuts, these locknuts have a free-spinning tooth lock washer that grips the material surface instead of threads for easy installation and mild vibration resistance.

Comparable in strength to Grade 8 bolts, these locknuts are about 25% stronger than medium-strength steel locknuts.

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

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

These locknuts have good chemical resistance.

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

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

Stainless steel locknuts have excellent corrosion resistance in most environments.

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

These locknuts include a two-piece clamp that expands to grip the bolt on all sides and a concave jam nut that clamps the threads onto the bolt for added vibration resistance. They're also known as drake-style nuts.

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

These flange locknuts have excellent resistance to chemicals and salt water.

These flange locknuts are comparable in strength to Grade 8 bolts.

These flange locknuts have excellent resistance to chemicals and salt water. They have an irregularly shaped thread that grips the bolt for a stronger hold than nylon-insert flange locknuts.

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

Fiberglass flange nuts are chemical resistant, nonconductive, and lightweight.

Stainless steel nuts have excellent corrosion resistance in most environments.

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

These coupling nuts have good chemical resistance.

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

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

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

These nylon 6/6 cap nuts are chemical resistant, nonconductive, and lightweight.

Low-profile cap nuts are about 20% shorter than standard cap nuts for use in low-profile applications.

The nylon cap covers and grips the threads to resist loosening.

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

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

Square weld nuts have more weld points than hex weld nuts for a stronger hold. Use them on flat surfaces.

Weld these nuts to uncoated steel surfaces.

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

About twice as strong as aluminum rivet nuts, these low-profile rivet nuts have a cadmium or tin-zinc plating for corrosion resistance.

Stainless steel nuts have excellent corrosion resistance in most environments.

These nickel-plated brass sealing nuts have good resistance to chemicals and salt water.

Use these tube-end weld nuts with left-hand threaded fasteners.

Made from brass, these inserts are nonmagnetic, mildly corrosion resistant, and electrically conductive.

Change inch threads to metric with these adapters, or swap metric threads for inch. An external hex lets you tighten or loosen them with a wrench.

Often called sleeve nuts, these thread adapters fasten parts with right-hand threads to parts with left-hand threads.

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.

Use these nuts with a sleeve and fitting to provide a tight metal-to-metal seal on steel tubing that is flared to 37°.

Also known as CGA nuts, these are designed for low-pressure welding applications downstream of your pressure regulator. Attach them to barbed hose fittings for compressed gas to make a threaded connection to torches or pressure regulators.

Use these tools to install most styles of rivet nuts. Use a wrench to hold the tool and a ratchet to tighten the nut.

Use adapters on the ends of forcing screws and face-grip puller legs when pulling shafts, bearing caps, and pinions.
