About Shafts

High-Strength Steel Threaded Rods

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.

Low-Strength Steel Threaded Rods

About half the strength of medium-strength steel threaded rods, use these for light duty hanging, mounting, and fastening.

Left-Hand Threaded Low-Strength
Steel Threaded Rods

Tighten these threaded rods by turning them to the left; once fastened, they resist loosening from counterclockwise motion. About half the strength of medium-strength steel threaded rods, use them for light duty hanging, mounting, and fastening.

18-8 Stainless Steel Threaded Rods

18-8 stainless steel threaded rods have good chemical resistance.

Super-Corrosion-Resistant 316
Stainless Steel Threaded Rods

More corrosion resistant than 18-8 and 410 stainless steel threaded rods, these 316 stainless steel rods have excellent resistance to chemicals and salt water.

Nylon Threaded 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.

Aluminum Threaded Rods

One-third the weight of steel, aluminum threaded rods resist corrosion in wet environments.

Brass Threaded Rods

Brass threaded rods are corrosion resistant in wet environments, electrically conductive, and nonmagnetic.

Titanium Threaded Rods

Titanium threaded rods have a high strength-to-weight ratio and are resistant to acids and salt water.

Partially Threaded Studs

Screw these studs into a tapped hole and use them as a pivot point, hinge, shaft, or locator pin.

Steel Press-Fit Studs

These steel studs are zinc plated to resist corrosion in wet environments.

Stainless Steel Press-Fit Studs

18-8 stainless steel studs have good chemical resistance.

Stainless Steel Wood Screw Threaded Studs

18-8 stainless steel studs have good chemical resistance and may be mildly magnetic. Also known as hanger bolts, use them to hang, mount, and fasten parts to wood structures.

Steel Wood Screw Threaded Studs

These studs are also known as hanger bolts—use them to hang, mount, and fasten parts to wood structures.

Weld Studs

Pass these studs through a hole and weld them in place.

Stainless Steel Right-Angle Weld Studs

These studs have good chemical resistance. Weld them to stainless steel surfaces.

Steel Right-Angle Weld Studs

Weld these studs to uncoated steel surfaces.

Rivet Studs

Add a stud to thin material when you only have access to one side.

Coupling Nuts

Low-Strength Steel Coupling Nuts

About half the strength of medium-strength steel coupling nuts, these nuts are for light duty fastening applications.

Medium-Strength Steel Coupling Nuts—Grade 5

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

18-8 Stainless Steel Coupling Nuts

These coupling nuts have good chemical resistance.

Super-Corrosion-Resistant 316
Stainless Steel Coupling Nuts

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

Aluminum Coupling Nuts

One-third the weight of steel, aluminum coupling nuts resist corrosion in wet environments.

Brass Coupling Nuts

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

Stainless Steel Extra-Long Coupling Nuts

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

Coupling Nuts with Sight Hole

Use the sight hole to check for proper thread engagement.

Female Thread Adapters

Inch-to-Inch Female Hex Thread Adapters

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

Left-Hand to Right-Hand Female Hex Thread Adapters

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

Inch-to-Metric Female Hex Thread Adapters

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.

Connecting Rods

Designed for use with right-hand, internally threaded rod ends, these rods have right-hand threads on both ends. Use them for remote valve operators, throttle controllers, shifting mechanisms, and virtually any push/pull assembly.

Internally Threaded Connecting Rods

Designed for use with right-hand, externally threaded rod ends, these rods have right-hand threads on both ends. Use them for remote valve operators, throttle controllers, shifting mechanisms, and virtually any push/pull assembly.

Linear Motion Shafts

Threaded Linear Motion Shafts

Mount these externally threaded shafts into tapped holes rather than using a shaft support, or attach a hex nut, shaft collar, or other threaded accessory.

Tapped Linear Motion Shafts

Internal threads allow you to mount these shafts onto threaded studs and fasteners, no shaft supports needed.

Step-Down Linear Motion Shafts

A shoulder near the end of the shaft allows for easy positioning of housings, shaft supports, and collars.

Linear Motion Shafts with Retaining Ring Grooves

Clip retaining rings into the grooves to separate and position collars, supports, and housings.

Rotary Shafts

Threaded Rotary Shafts

Attach threaded accessories, such as mixer propellers and fan blades, to the end of these shafts.

Flange-Mount Idler Rotary Shafts

Mount the flange to a machine or wall to support idler sprockets and pulleys in tensioning applications. They include washers and a nut to position your component and hold it in place.

Tapped Rotary Shafts

Connect these internally threaded shafts directly to threaded components, or use a fastener to secure.

D-Profile Rotary Shafts

A flat surface area allows set screws to dig into the shaft for securely mounting gears, sprockets, and bearings.

Step-Down Rotary Shafts

A shoulder near the end of the shaft provides a stop for gears, sprockets, and bearings.

Keyed Rotary Shafts

Combine with a machine key to transmit torque to gears, sprockets, and other power transmission components.

Rotary Shafts with Retaining Ring Grooves

Clip retaining rings into the grooves to separate and position gears, sprockets, and bearings.
