A lead screw (also called a power screw or translation screw) is a threaded rod used to transform rotational motion into precise linear motion

• Mechanics: The screw’s threads engage with a matching nut, creating linear displacement when rotated.

• Thread Types: Common forms include square, buttress, round, and Acme (trapezoidal) threads

• Applications:

  • Linear actuators

  • Machine slides (CNC machines, lathes)

  • Vises, presses, and jacks

  • Medical devices requiring controlled movement
