A wedge is a double sided screw basically. Therefore, the difference is the number of sides.
Picture a nut on a screw. You are holding the nut so it can't turn, but allow it to go up and down the screw. The screw is restrained so it can turn, but not move back and forth. As you turn the screw one way and the other, the nut will move up and down the screw. That is a trivial example of one very common screw thread mechanism.
screw thread are single threads which means they are not double
A machine screw typically has a slotted or Phillips drive whereas a cap screw typically has a socket or torx head.
a cap screw has a top bigger than the threaded portion [a cap]. the cap screw does not sit flush with the material being screwed into. a machine screw has a tapered top that fits into a countersunk hole and when screwed in is flush with the surface being screwed into;
If it assembled into a tapped hole, it is a screw. It is tightened (torqued) at the head. If it used witha nut, it is a bolt. It is tightened (torqued) at the nut. Otherwise, it is the same piece of hardware, only the use is different
when a spiral groove is cut over a hole, then it is nut thread. when a spiral groove is cut over a shaft, then it is screw thread.

None
Breakaway torque is the torque required to start the initial movement, in the loosening direction, of a bolt, screw, or nut from its (non−loaded) at rest position with the locking element engaged. Tightening torque is the torque necessary to move the bolt, screw, or nut along its threaded length in the tightening direction.
The one screw basically.
A Brazilian nut plays FUTBOL, while an Austrailian nut plans RUGBY.

nothing much.
Yes, a bolt is a type of screw with a threaded shaft and a head that is designed to use with a nut for fastening purposes. The main difference between a bolt and a screw is that a bolt typically requires a nut to secure two objects together, while a screw can typically be inserted directly into a material.

The efficiency of a screw jack can be increased by reducing friction between the screw and the nut through proper lubrication, using a finer pitch screw for smoother operation, and ensuring that the screw and nut are properly aligned to minimize binding. Additionally, using a larger diameter screw can help distribute the load over a larger area, reducing wear and improving efficiency.
