Sometimes the propeller on a boat is called a screw & they used to be made of lead. So they would be found at the end of the propeller shaft.

when lead of the screw is equal to the pitch it is called single threaded screw

The lead screw moves the turret by a precise increment for every rotation of the screw. This allows the machine to generate threads in a workpiece, to generate precise length and diameter dimensions, and to maintain a constant rate of metal removal.
That would be a "phillips" heades screw.
The number of revolutions needed to move a screw block 1 inch depends on the screw's lead, which is the distance the screw moves linearly with one full revolution of the crank. For instance, if the screw has a lead of 0.1 inches, it would take 10 revolutions to move the block 1 inch. To determine the exact number of revolutions, you would divide 1 inch by the lead of the screw.

The lead of a screw refers to the distance a screw advances in one complete turn. It is determined by the screw's pitch, which is the distance between corresponding points on adjacent threads. A screw with a larger lead will advance more with each turn compared to one with a smaller lead.

Yes, a lead screw is used in a typewriter as part of its mechanism to move the carriage horizontally. When a key is pressed, the lead screw is turned, which advances the carriage to position the paper correctly for typing. This mechanical movement allows for precise alignment of the typebars with the paper. Overall, the lead screw is essential for the typewriter's operation and functionality.
The lead screw moves the turret by a precise increment for every rotation of the screw. This allows the machine to generate threads in a workpiece, to generate precise length and diameter dimensions, and to maintain a constant rate of metal removal.
presuming you mean the lead screw on a lathe, used when cutting threads on the workpiece, then the screw itself is obviously fixed, but the rotation of it may be able to be changed, depending on the lathe manufacturer.

An example of a screw would be a jarlid.

A screw has 7 sides and 7 angles. therefore a heptagon can be found as a screw
