Do longer screwdriver have more torque?
A: This may seam odd, but the different length of screwdriver really doesn’t affect the torque directly. Torque is the force applied times the distance from the axis you are rotating about. The long handle will move your hand further from the rotation and give you more torque.
Why do we prefer screw driver having long arms?
Answer: Torque or turning effect due to a force is maximum when r is maximum. We prefer to use a wrench with long arm because when the length of the arm(r) is long, the force (F) required to produce a given turning effect ( x ) is smaller. Hence, a nut can be unscrewed easily.
How much torque can a human generate with a screwdriver?
All have a torque-limiting clutch that disengages once the preset torque has been reached. Torque screwdrivers can exert torques from 6 inch ounces (0.04 N⋅m) to at least 27 N⋅m.

Long screwdrivers are easier to turn because the grip is in the palm of the hand, thus allowing all fingers to contribute. A shorter screwdriver is turned with the thumb and first two or three fingers, providing much less torque.

Does a longer screwdriver have more leverage?
Longer, (read bigger) screwdrivers tend to have bigger handles. The lever you are using to loosen a screw is the radius of the handle. The bigger that is, the more leverage you have.
Why does a carpenter use a screwdriver of long and thick handle?
requiring less power than a short one lies in the facts we have described—partly in its having a larger handle, whereby power is more readily communicated, and partly because a larger handle, in effect, is given to the screw-driver by its handle being moved in a circle.
Why do flat head screws still exist?
