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.

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.

Join two female-threaded parts of various thread types and sizes, while allowing air, liquids, wire, or other thin materials to pass through.

Change thread sizes or types, such as fine to coarse threads, on parts without changing gender.

In addition to joining male- and female-threaded parts, these adapters can increase or decrease metric thread sizes and change the thread pitch.

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

Known as setup studs, these studs withstand sideways forces better than fully threaded studs because they have a strong unthreaded middle.

Also known as tap-end, fixture, and setup studs, these studs have Class SK6 friction-fit threads on one end to resist loosening and Class 6g standard threads on the other end for attaching a nut.

These metric 316 stainless steel studs have excellent resistance to chemicals and salt water. Also known as hanger bolts, use them to hang, mount, and fasten parts to wood structures.

Turn these studs with a hex key for ease of installation.

Position components in assemblies, as well as separate or connect parts with these standoffs.

These standoffs are made to NAS specifications.

Multiple thread channels (also known as thread starts) create faster linear travel than lead screws with a single thread start.

Also known as single-start and self-locking lead screws and nuts, these have a single thread that runs the length of the screw. The nut travels only when the screw turns, so your system won't unexpectedly move when the lead screw is at rest.

Keep your ball screw spinning without the ball nut damaging your system. When the ball nut reaches the stop pin at either end of the ball screw, it disengages and begins to idle.

A crisscross thread pattern allows you to drive the nut back and forth without changing the lead screw's direction of rotation. When the nut reaches one end of the lead screw, it changes direction and travels back to the other end.

Similar to turnbuckles, these rods have right-hand threads on one end and left-hand threads on the other so you can make a linkage that adjusts for tension. Add right- and left-hand threaded rod ends to build your linkages.

Typically used with low-pressure stainless steel threaded pipe fittings.

Typically used with high-pressure brass and bronze threaded pipe fittings.

Typically used with high-pressure brass and bronze threaded pipe fittings.

Typically used with medium-pressure brass and bronze threaded pipe fittings.

When you're unsure of the exact thread type you need, these fittings have universal threads that are compatible with the most common ones (NPT, NPTF, BSPP, BSPT).

Typically used with low-pressure brass and bronze threaded pipe fittings.

Typically used with medium-pressure iron and steel threaded pipe fittings. Also known as Schedule 80.

Pipe has clockwise (right-hand) threads on one end and counterclockwise (left-hand) threads on the other end. When you use a wrench to turn, connections on both ends tighten at the same time.

A plastic sleeve prevents destructive corrosion when connecting different metals.

Typically used with high-pressure galvanized iron and steel threaded pipe fittings. Also known as Schedule 160.

Typically used with low-pressure aluminum threaded pipe fittings.

This polypropylene pipe resists the damaging effects of ultraviolet light, so it’s suitable for outdoor use. It has the chemical resistance to withstand acids, solvents, and other harsh substances.

Connect to thick-wall plastic pipe fittings for use in heavy duty industrial plumbing and water supply applications, such as water processing, waste water treatment, and irrigation. Pipe can handle pressures up to 900 psi.

Join pieces of conduit.
