it applies torque to fulfill its design capabiities
There is no advantage whether the handle is 1.2 cm or 10 cm, the screw will still only make one revolution. The reason being is that both the screw driver and the screw become part of the whole. The only increase in the screws revolutions is if the screw driver is geared to make more than one turn of the screw.

Mechanical advantage the resistance force. Mechanical advantage is equal output force divided by input force.
Mechanical advantage=load/effort
The mechanical advantage of a screw can be found by dividing the circumference of the screw by the pitch of the screw. In this case, the total mechanical advantage is equal to the circumference of the simple machine to which the effort force is applied divided by the pitch of the screw.
The mechanical advantage of a screw is determined by comparing the distance traveled along the screw's threads to the force applied to turn the screw. It is calculated as the ratio of the circumference of the screw to the pitch of the screw thread. A higher mechanical advantage indicates that less force is needed to lift a load.
The mechanical advantage equation for a screw is calculated by dividing the circumference of the screw (distance traveled per revolution) by the pitch of the screw (vertical distance traveled per revolution). The formula is MA = 2πr / p, where MA is the mechanical advantage, r is the radius of the screw, and p is the pitch of the screw.
Mechanical advantage for the six simple machines are: Lever: Mechanical Advantage = Length of Effort Arm / Length of Load Arm Pulley: Mechanical Advantage = Number of ropes supporting the load Wheel and Axle: Mechanical Advantage = Radius of Wheel / Radius of Axle Inclined Plane: Mechanical Advantage = Length of Incline / Height of Incline Wedge: Mechanical Advantage = Length of Sloping Side / Thickness of Wedge Screw: Mechanical Advantage = Circumference of the screw / Pitch of the screw
The mechanical advantage of a screw is given as MA = circumference / pitch. The pitch of the screw is the number of threads per centimeter. The circumference is measured at the working portion of the screw, not the head.
There is no advantage whether the handle is 1.2 cm or 10 cm, the screw will still only make one revolution. The reason being is that both the screw driver and the screw become part of the whole. The only increase in the screws revolutions is if the screw driver is geared to make more than one turn of the screw.
Ideal Mechanical Advantage can be found using this formula IMA = DE / DR . Ideal Mechanical Advantage is a theoretical calculation, AMA,Êactual mechanical advantage is calculated with this formula, AMA = R / Eactual .
You divide the pitch of the jack's screw into a length equal to the distance traveled by the end of the Jack's lever around the circumference of a circle having a radius equal to the jack's lever. Elliott

Holding the diameter of the screw constant, closely spaced threads (fine pitch) have a higher mechanical advantage than thread which are spaced farther apart (course pitch). Mechanical advantage is the ratio of travel of the applied force to the ratio of the imparted force. Because the screw must rotate more times to insert a given depth, fine pitch has a higher mechanical advantage.
An magnetized screwdriver is an advantage for an electrician because it means the screw will remain attached to the screwdriver meaning it will be easier to unscrew. Hope this helps ;)
