Bobbywhy said:This is known as a "motorized lead screw". The torque to drive it depends on the load you are moving plus the friction of the system.

Bobbywhy said:balsaboom Excuse me, I did not read your post carefully and missed your point completely. So, you are looking for “couplings to link the motor shaft (4mm / 5/32") to the 1/4" threaded rod”.
What you can use is called an “Inch/Metric Universal Lateral Shaft Coupler”. Here is a catalog with many to choose from:
PIC Design Catalog 45, Lateral shaft couplers, Section 7 which contains these types:
Bellows Couplings, Zero Adjustable Couplings, Flexible Couplings, Miniature Oldham Couplings, Wafer Oldham Couplings, Universal Lateral Couplings, Multi-Jaw Couplings, Precision Universal Joint Couplings, Molded Universal Joint Couplings, Precision Sleeve Couplings, Flexible Zero Backlash Couplings, Spider Couplings
You’ll need to get the pdf document and then scroll down to Section 7. There you can choose the right one for your project.
Good Luck, Bobbywhy
The motor is connected to the threaded rod through a coupling or gearbox. When the motor is turned on, it rotates the threaded rod, causing it to move in a linear motion.
Using a motor allows for precise and consistent movement of the threaded rod, which is useful for tasks such as lifting, rotating, or tightening objects. It also reduces the amount of manual labor required for these tasks.
The most common types of motors used are stepper motors and servo motors. These motors provide accurate control and can be easily programmed for specific movements.
Yes, as long as the motor has enough torque and power to rotate the threaded rod. The size and type of threaded rod will determine the type and size of motor needed.
Yes, it is important to ensure that the motor is properly secured and that there are no loose or exposed parts that could cause injury. It is also important to follow all safety guidelines when operating the motor and to regularly maintain and inspect the equipment.
