These flanges are for low-pressure applications in noncorrosive environments.

The male threads on these fittings have a sealant applied for extra leak protection.

A galvanized finish gives these fittings better corrosion resistance than our plain steel high-pressure fittings. Also known as Pressure Class 3000 fittings.

Made to tighter tolerances than other steel pipe fittings, these are also known as instrumentation fittings.

A galvanized finish gives these fittings fair corrosion resistance. They have the strength to handle medium-pressure applications.

Crimp these fittings onto steel pipe to form a tightly sealed connection that’s faster than threading or welding and doesn’t require heat.

Socket-connect fittings are easier to weld than butt-weld fittings because the fitting doesn't need to align perfectly to the pipe. Slide the pipe into the socket and weld.

Unlike other manifolds, which have an inlet on either end, these have one inlet on the opposite side from the outlets. This design allows air or fluid to follow a straight path, improving flow through your system. Also known as headers.

Use these fittings in an air vacuum system to avoid the hassle of brazing and welding. Insert two fittings into a clamp and tighten to form a secure seal in steel tubing.

Metal hose fittings have better durability than plastic barbed hose fittings.

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 6,000 psi

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

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.

Connect two differently sized male-threaded parts, such as threaded rods, and tighten with a standard 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.

These assortments include various sizes of thread-locking inserts.

Adhesive on both the internal and external threads keeps these inserts in place and holds screws tight.

The strongest key-locking inserts we offer, these inserts are made to stringent military specifications.

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

The knurled body holds these inserts in place in aluminum and other soft metals. Use an arbor press to install them in untapped holes.

Knurls hold these inserts in hardwoods such as oak, maple, and walnut to prevent twisting.

Steel inserts have high strength for durability.

Fewer prongs than other tee nut inserts reduce the risk of splitting hardwood—these inserts have three short prongs.

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

A hex-shaped body provides the highest twist resistance of any rivet nut.

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

The coated flange seals out moisture and prevents corrosion.

About twice as strong as aluminum rivet nuts, these rivet nuts are zinc plated for mild corrosion resistance.

Once installed these rivet nuts have a large back flange that distributes the load across a broad area for a strong hold in plastic and composites.

Stronger than stainless steel, these nuts are comparable in strength to Grade 9 bolts.

Protect bolts from sideways (shear) pressure.

Use these rivet nuts for light duty fastening in low-clearance applications. Assortments include rivet nuts, mandrels, and an installation tool.

Reduce the knockout size in an outlet box or enclosure so you can attach a different size of conduit to it.

A magnet holds the socket, making changes quicker.

Pull the collar to quickly attach and remove sockets.

Convert from one square drive size to another.

These adapters are insulated to protect against accidental contact with live electrical circuits. They are tested to 1,000 volts to meet IEC 60900.

The angled shape lets you use your bit driver like a wrench.

Set a desired torque within the range.

Pivot the head to access fasteners from an angle.

Prevent overtightening that can damage fasteners. These adapters spring back slightly when the set torque is reached.

Convert from one square drive size to another.

A spiral seam gives this duct greater strength and rigidity than standard duct.

Fittings have gaskets which create a tight seal—you don't need to seal joints with coating or tape.

These noise reducers mount directly to spiral duct to decrease noise by as much as 50%.

A strip of flexible spring steel wraps around the teeth of both hubs to absorb sharp, momentary load increases that can come from motor startups, emergency braking, or sudden impact with hard objects.

The thick split spider on these couplings takes on twice as much torque as standard split spiders, while a set screw holds the hubs in place on your shaft. Also known as jaw couplings, use them to connect motors to pumps, mixers, and other high-torque equipment.

With a rigid gear design, these steel couplings transmit more torque than other couplings of the same size.

Use these gear-shaped couplings for high-speed and high-torque applications.

Designed to grip evenly around your shaft, clamping couplings provide more holding power than set screw couplings without marring the shaft.

When one of your shafts is undersized from wear, oversized from coatings, or uncommonly sized, machine one end of these couplings to fit. They clamp around your shafts for a secure hold that won’t cause damage.

Set screws bite into your shaft to hold these couplings in place.

For hard-to-access shafts that are oversized from coatings or undersized from wear, we’ll get you a coupling in the right size that clamps on as two pieces, so you don’t need to move your shafts or installed components.

Machine the pilot hole in these couplings to whatever size you need. Often used for shafts that are undersized from wear or oversized from coatings. These couplings are two-piece, so you can remove and reinstall them without moving your shafts.

Increase the diameter of your shaft while also making it longer.

One side is unfinished for milling custom pulleys, threaded hubs, sprockets, collars, knobs, sensor targets, or just about anything imaginable; the other side is a one-piece clamping coupling for mounting whatever you’ve created to your shaft.

A toothed slot lets these bushings contract for insertion into the bore of your sprocket or pulley and then expand for a snug fit.

Reduce the diameter of a blade's arbor hole to fit your saw's arbor.
