Tapped Linear Motion Shafts
Internal threads allow you to mount these shafts onto threaded studs and fasteners, no shaft supports needed. These shafts work with linear bearings to reduce friction in manual and automated systems because they're smooth, hard, and wear resistant. You'll often see them in packing, machine tool, and material handling operations. All are turned, ground, and polished to tight diameter and straightness tolerances.
The surface is hardened, so they stand up to repeated motion while keeping their center soft enough to absorb stress from shifting loads. Chamfered edges remove sharp corners at the end of these shafts, reducing damage to bearings, housings, and other components during installation.
Alloy steel shafts are stronger and resist wear better than stainless steel.
Surface smoothness—The lower the microinch value, the smoother the finish and the less friction and wear it will cause on the bearing.

Flat-Vent Pull-Out Dowel Pins
The flat side of these pins relieves trapped air, making them easier to insert and remove from blind holes. One end is tapped and the other is chamfered for easy insertion. To remove, thread a screw or tool into the tapped hole, then pull them out. Use them as pivots, hinges, shafts, jigs, and fixtures to locate or hold parts. Pins are precision ground for accurate alignment. Breaking strength is measured as double shear, which is the force required to break a pin into three pieces.
Metric pins meet DIN standards.

Metric Threaded on One End Studs
Screw the threaded end of these metric studs into a tapped hole and use the unthreaded end as a pivot point, hinge, shaft, or locator pin. All can be installed and adjusted by hand or with a slotted screwdriver. These studs are steel for strength and wear resistance. They’re best for dry environments, since moisture will cause them to rust. All meet ISO 2342 (formerly DIN 427), an international standard for fastener dimensions.

Connecting Rods
Designed for use with right-hand 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.
Carbon steel rods without a plating are best for dry environments, since moisture will cause them to rust.
Aluminum rods are lightweight and corrosion resistant in wet environments.
18-8 stainless steel rods have good chemical resistance.

Metric Fast-Travel Ultra-Precision Lead Screws and Nuts
Multiple thread channels (also known as thread starts) create faster linear travel than lead screws with a single thread start. Operating with less backlash (play) than Metric Precision Acme Lead Screws and Nuts, these lead screws and nuts provide increased nut life and more reliable movement in automated systems. To ensure compatibility, select components that have the same thread size, thread pitch, and number of thread starts.
Lead screws with one machinable end let you create your own custom connection to suit your application.
Lead screws with one coupling end connect directly with your shaft without extra machining. Torque down the locknut once inserted.
Flange nuts with a wear-compensating internal O-ring resist backlash to keep the nuts in place and maintain a tight fit even when their threads begin to wear. They’re often used in 3D printing and robotic applications.
Travel distance per turn, also known as screw lead, is the distance a nut moves with one revolution of the lead screw.

Metric Ultra-Precision Lead Screws and Nuts
Operating with less backlash (play) than Metric Precision Acme Lead Screws and Nuts, these provide increased nut life and more reliable movement in automated systems. Also known as single-start and self-locking lead screws and nuts, they 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. To ensure compatibility, select components that have the same thread size, thread type, thread size, thread pitch, and number of thread starts.
Lead screws with one machinable end let you create your own custom connection to suit your application.
Lead screws with one coupling end connect directly with your shaft without extra machining. Torque down the locknut once inserted.
Flange nuts with wear-compensating internal O-ring maintain a tight fit even when their threads begin to wear. They resist backlash to maintain accuracy over time, which is important in positioning applications such as 3D printing and robotics.
Travel distance per turn, also known as screw lead, is the distance a nut moves with one revolution of the lead screw.
