These nuts have good chemical resistance.

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 Grade 8 locknuts are about 25% stronger than medium-strength steel thin locknuts.

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

Threads at the top of these locknuts expand to grip the bolt on all sides for a stronger hold than distorted thread locknuts.

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

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

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.

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

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.

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.

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

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

Stainless steel nuts have excellent corrosion resistance in most environments.

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

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

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.

An irregularly shaped thread grips the bolt for a stronger hold than nylon-insert cap locknuts.

Weld these nuts to flat and uneven uncoated steel surfaces for a strong permanent hold.

Weld these nuts to stainless steel surfaces.

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

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

These thumb nuts have good chemical resistance. The flange distributes pressure over a large area to reduce stress on your part.

Stainless steel nuts have excellent corrosion resistance in most environments.

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

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

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

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.

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.

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.

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

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.

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.
