Lead Screws and Screw Jacks

Ball Screws and Nuts

Also known as single-start ball screws and nuts, these have a single thread that runs the length of the screw. They operate with more torque than fast-travel ball screws and nuts.

Fast-Travel Ball Screws and Nuts

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

Self-Stopping Ball Screws and Nuts

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.

Corrosion-Resistant Ball Screws and Nuts

Also known as single-start ball screws and nuts, these have a single thread that runs the length of the screw. They operate with more torque than fast-travel ball screws and nuts.

Fast-Travel Corrosion-Resistant
Ball Screws and Nuts

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

End Supports for Lead Screws and Ball Screws

A set of ball bearings reduces friction and secures the end of a ball or lead screw.

Electric Actuators

Positioning Slides for Stepper Motors

Add your own stepper motor and controller to precisely move the ball screw and carriage smoothly at high speeds, like a head on an inkjet printer.

Dry-Running Positioning Slides for Stepper Motors

With PTFE sleeve bearings and a low-friction ball screw, these slides don’t require the mess and maintenance of lubrication but still give you precise positioning anywhere along the length of their stroke.

Screws and Bolts

Alloy Steel Low-Profile Swivel-Tip Set Screws

These set screws have a low-profile flat-faced ball tip for use in low-clearance applications.

Stainless Steel Low-Profile Swivel-Tip Set Screws

Stainless steel set screws have excellent corrosion resistance in most environments.

Swivel-Tip Set Screws

The tip is narrow to pass through threaded holes.

Large-Diameter Swivel-Tip Set Screws

A wide tip provides more gripping power than standard swivel-tip set screws. To use, remove the tip, thread the screw through the hole, and attach the tip on the other side.

Large-Diameter Swivel-Tip Thumb Screws

A wide tip provides more gripping power than standard swivel-tip thumb screws. To use, remove the tip, thread the screw through the hole, and attach the tip on the other side.

Swivel-Tip Thumb Screws

For maximum contact with angled and uneven surfaces, the tip swivels in all directions. The tip is narrow so it will fit through threaded holes.

Ultra-Flexible Swivel-Tip Thumb Screws

A large swivel angle allows these thumb screws to make better contact with angled and uneven surfaces than nonremovable swivel-tip thumb screws.

Clamping and Workholding

Swiveling Tips for Screws and Threaded Studs

Attach to the end of a screw or threaded stud to apply uniform pressure on uneven and angled surfaces. Also known as toggle and swivel-foot pads.

Nonmarring Swiveling Tips for
Screws and Threaded Studs

The contact area is covered in plastic to protect soft metal and polished surfaces. Attach these tips to the end of a screw or threaded stud to apply uniform pressure on uneven and angled surfaces. Also known as toggle and swivel-foot pads.

Swiveling Gripper Tips for
Screws and Threaded Studs

Attach to the end of a screw or threaded stud—the serrated face swivels to grip uneven and angled surfaces. Also known as toggle and swivel-foot pads.

Swiveling Locating and Support Buttons

The swiveling tip supports uneven and angled surfaces.
