Also known as live swivels, these fittings swivel continuously 360° before and after installation. This not only makes installation easier, but also eliminates the twisting and kinking that can cause hose failure. Fittings are threaded on both ends so you can connect them directly to a threaded hose or to pumps, cylinders, and other equipment in your hydraulic system. Use in high-pressure applications up to 5,000 psi.

Use these couplings at pressures up to 5,000 psi. They consist of a plug and socket that connect and disconnect quickly. Use them if you need frequent access to a line. They are compatible with International Standard ISO B-shape plugs and sockets.

One side inch, one side metric, and a hex in the middle—these handy fasteners connect two female-threaded parts, such as coupling nuts, adapting from inch threads to metric. Tighten with 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.

Twist these adapters onto female metric threads to change pitch or switch thread sizes.

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.

The through hole allows you to connect float rods to float valves.

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.

Increase or decrease metric thread size from one male-threaded part to another. Commonly used to connect two differently sized threaded rods, they have a hex-shaped body, so you can tighten them with a standard wrench.

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

A flat hex head sits flush against the material surface for use in low-clearance applications.

Also known as clinch style captive nuts, press these nuts into a drilled or punched hole with an arbor press or similar pressure tool.

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

Also known as broach style captive nuts, these nuts have good chemical resistance and may be mildly magnetic.

Weld these nuts to uncoated steel surfaces.

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

Projections on the base concentrate the weld and provide room for heat to dissipate.

Weld these nuts to stainless steel surfaces.

Weld these nuts to stainless steel surfaces.

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

The tapered shape makes it easier to guide these inserts into a hole during installation. Use a drill bit to create a straight hole, then taper the top half.

Install these inserts into plastic parts to create a secure base for fasteners.

The flange keeps these inserts from pulling through a hole. Press them in from the underside of material, and install a screw from the top of material.

Made from brass, these inserts are electrically conductive, nonmagnetic, and have good corrosion resistance.

These aluminum inserts are 70% lighter than brass inserts, electrically conductive, and nonmagnetic. They have good corrosion resistance, which is comparable to brass but not as good as stainless steel.

These 18-8 stainless steel inserts have better corrosion resistance than brass inserts and may be mildly magnetic.

The barbed sides keep these securely in place even before a screw is installed.

These aluminum inserts are 70% lighter than brass inserts, electrically conductive, and nonmagnetic. They have good corrosion resistance, which is comparable to brass but not as good as stainless steel.

These inserts have a high strength-to-weight ratio and resist acids and salt water better than nickel alloy and stainless steel inserts.

Without a prong to break off and retrieve, these inserts are often used where debris could cause damage.

Eliminating the need for primer, these inserts are coated to resist corrosion when installed in different materials.

Made of Nitronic 60 stainless steel, these inserts prevent the screw from binding or sticking without any coating or lubricant that could contaminate particle-free environments.

Assortments include various sizes of helical inserts and a tap, a drill bit, and an installation tool for each thread size.

A dry film keeps the screw from sticking or binding in these inserts during installation.

The flange keeps these inserts from being pulled through a hole and provides a load bearing surface.

Assortments include various sizes of tapping inserts for softwood.

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

Hooked prongs give these inserts excellent holding power even when removing screws.

Steel inserts have high strength for durability.

A closed end seals out elements and protects the threads on these inserts from debris.

Mount these inserts flush or below the material's surface.

These inserts come with an installation tool. Drive the keys into the surrounding material for a more secure hold than thread-locking inserts.

Forming the strongest hold of any of our threaded inserts, these inserts have a distorted internal thread to lock screws into place and keys that drive into surrounding material to prevent slipping and rotating.

A closed-end tap, drill bit, and installation bit are included with these inserts.

These inserts are the most corrosion-resistant thread-locking inserts we offer.

Made of 18-8 stainless steel, these inserts have better corrosion resistance than black-phosphate steel.

Comparable to Grade 8 steel, these threaded rods have a tensile strength of 150,000 psi, making them about 25% stronger than medium-strength steel rods.

Made from nylon 6/6, these threaded rods resist oil, grease, and solvents. They’re nonconductive, making them good for use around sensitive electrical components.

These acetal threaded rods won't absorb moisture like nylon and fiberglass rods, so they're good for use in wet environments. They resist alcohol, gasoline, and solvents.
