Ball Screws and Nuts


	Ball Nuts Flange Nut Style C

Internal ball bearings provide smooth low-friction travel in applications that require high speeds, accurate positioning, and repeatable movement. Also known as single-start ball screws and nuts, they have a single thread that runs the length of the screw. They operate with more torque than fast-travel ball screws and nuts. To ensure compatibility, select components that have the same thread direction and size. Ball nuts are furnished with a tube to keep ball bearings in place. Do not remove the tube until you are ready to install the nuts onto the screws.

Bearing Locknuts

Carbon Steel

With a nylon insert that grips your threaded shaft or spindle without damaging its threads, these locknuts—also called shaft nuts—hold bearings, bushings, gears, and pulleys prone to vibration tightly in place. They come as one piece, so you can easily clamp them onto your shaft or spindle. But, since they aren’t made entirely of metal, they don’t stand up to heat as well as all-metal locknuts. Slots in their sides mean you can tighten and loosen them with a spanner wrench or spanner socket. Their face is also chamfered to help keep the size and weight of your assembly at a minimum. All meet international standards for bearing locknut dimensions.

Zinc-Plated Carbon Steel—Zinc-plated carbon steel locknuts resist rusting from some moisture, but you shouldn’t use them with salt water or chemicals. They are strong and resist wear, though they don’t stand up to corrosion as well as 303 stainless steel locknuts.

Thread Spacing—When choosing your thread spacing, consider the precision of your application. The finer the threads, the more control you have when making adjustments.

Quarter-Turn Quick-Change Fixture Clamps

Install these clamps into fixture plates, machine subplates, and tombstones to quickly swap components in or out of your machining setup. They lock or unlock with the turn of a knob. Since they locate while they clamp, you can accurately position components with repeatability of ±0.1".

For accurate positioning, use at least two sets of clamps and cam receptacles. Install receptacles into a base plate and clamps into a fixture plate. Line up the two plates, insert the clamps into the receptacles, then turn the knobs to secure your fixture in place. If you need more holding capacity, use additional clamps and receptacles.

Cam Receptacles

Steel Socket Nuts

Also known as Allen nuts, use these with socket head cap screws in recessed holes and tight spaces that don't have enough clearance for a wrench. Tighten them with a 6-point hex key. They can also be used as an insert by pressing or drawing them into nonhardened steel, cast iron, or soft nonferrous metal or by molding them into plastic, ceramic, fiber, and similar materials. Made from alloy steel, they're comparable in strength to Grade 9 bolts.

Tapping Threaded Insert Assortments for Soft Metal

Cut a variety of thread sizes into aluminum and other soft metal—no taps required. These inserts cut their own threads and lock into material, so they won’t budge when you install or remove a screw. To install inserts with a wrench, thread an insert and two hex nuts onto a bolt. Then, grip and turn the top nut to drive into a drilled hole. If you need to add a lot of threaded connections quickly, use an installation tool (not included) with a ratchet wrench or drill press. These inserts are comparable to Tap-Lok inserts.

Key-Locking Threaded Inserts for Soft Metal

Add strong threads in soft metal, such as aluminum. The keys on these inserts drive into holes to hold more securely than thread-locking or helical inserts. They prevent slipping and rotating, so they’re stable enough for use in vehicle or aerospace parts that experience heavy vibration. These inserts are comparable to Keensert inserts.

To install, drill and tap a hole in your material. Then, thread the insert onto the installation tool and screw it into the hole. Place the tool over the keys and hit it with a hammer to drive them in.

Standard Wall—Stronger than thin-wall inserts, these are your go-to choice for threading most holes.

Black Phosphate-Coated Steel—These inserts resist occasional moisture.

Thin-Profile Bearing Nuts

Used in pairs or with another bearing nut, these thin-profile nuts—often called shaft nuts—hold bearings, bushings, pulleys, and gears in place on your threaded shaft or spindle. Threading two nuts tightly against each other makes it harder for vibration to loosen your assembly than if you used only one nut. For the nut closer to the bearing, position the stepped face towards the bearing. These thin-profile nuts have holes on the side, so you can tighten and loosen them with a pin spanner wrench. All meet DIN 1816, an international standard for bearing locknut dimensions.

Carbon Steel—Carbon steel bearing nuts are strong and resist wear.

More compact than hydraulic cylinders with external tie rods, these cylinders have a round body that fits better into tight spaces and have a more streamlined appearance. To further minimize their footprint, they operate without an air cushion. These cylinders are double acting, meaning they both push and pull loads. They use two hydraulic ports, one to extend the piston and one to retract it. Because the piston is magnetic, these can be used with sensors (sold separately) to indicate piston position.

Thread-Locking Threaded Inserts

With Loctite® adhesive already on the threads, these inserts won’t back out or vibrate loose. The adhesive reaches full strength after 72 hours. Unlike helical inserts, you can install them with a standard drill and tap. However, thread-locking inserts are difficult to remove and reuse.

After drilling and tapping your hole, install inserts with a wrench or an installation bit. To use a wrench, thread an insert and two hex nuts onto a bolt. Then, grip and turn the top nut to drive into the hole. For slotted inserts, you can drive with a slotted screwdriver instead.

Standard Wall—Stronger than thin-wall inserts, these are your go-to choice for threading most holes.

Helical Threaded Inserts

Pronged

Restore, reinforce, or create threads in metal. The tough coils on these inserts expand once installed to anchor in a tapped hole. Also known as Heli-Coil inserts, they're often used in engine heads and machinery housings where strong connections are critical. Unlike threadlocking inserts, you can remove and reuse them without them losing their strength.

Installation requires a drill bit, a helical insert tap, and an installation tool.

Pronged—The prong attaches to an installation tool for precise control as you drive inserts in. Remove the prong with a punch or break-off tool before inserting a screw.

Bearing Nuts

Carbon Steel

Stepped Face

Often paired with spring lock washers to strengthen their hold, these bearing nuts—also known as shaft nuts—keep vibration from shifting bearings, bushings, pulleys, and gears on your threaded shaft or spindle. They have slotted sides, so you can tighten and loosen them with a spanner wrench or spanner socket.

Carbon Steel—Carbon steel bearing nuts are strong and resist wear.

Stepped Face—Use stepped-face bearing nuts with DIN 462 spring lock washers. You can also use them in pairs or with other bearing nuts. For the nut closer to the bearing, position the stepped face towards the bearing. All meet DIN standards for bearing lockout dimensions.

Thread Spacing—When choosing your thread spacing, consider the precision of your application. The finer the threads, the more control you have when making adjustments.

Tapping Threaded Inserts for Soft Metal

No need to tap the hole, these inserts cut their own threads into soft metal, such as aluminum. The teeth dig into the material to keep them secure when installing and removing screws. To install inserts with a wrench, thread an insert and two hex nuts onto a bolt. Then, grip and turn the top nut to drive into a drilled hole. If you need to add a lot of threaded connections quickly, use an installation tool with a ratchet wrench or drill press. These inserts are comparable to Tap-Lok inserts.

Standard Wall—Stronger than thin-wall inserts, these are your go-to choice for threading most holes and replacing drilled out threads.
