A Basic Screw Jack Design The concept of a screw jack is quite simple and easy to understand. A screw jack is a mechanical device that uses a helical threaded shaft or screw to provide linear motion, typically used for lifting heavy objects. Its operation is based on the principle of a nut being screwed onto a bolt, resulting in an increase in the distance between its ends. This basic design can be easily replicated and is widely utilized across various industries.
