Does Longer Screwdriver Increase 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.

How do you get more torque on a screwdriver?

For example, to get a stubborn screw out, don't get a longer screwdriver. Put vice grips on the screwdrivers and then turn. The distance from the fulcrum (center of the screw) increases roughly by the length of the vice grip, thus increasing torque.

Are longer screwdrivers stronger?

Everyone who deals with screws and screwdrivers knows that long screwdrivers are stronger than short ones. However, I can't find any relationship between length of a screwdriver and mechanical advantage. For a wrench, it's obvious: Long arms produce more torque. But in case of a screwdriver, it is not so simple.
