Why does a screwdriver allow you to turn a screw you couldn't turn by hand?

A screwdriver allows you to exert more torque on a screw. Torque is defined as the product of the force exerted and the distance from the center of rotation. Torque is essentially a rotational force. It is simple to increase torque, simply increase the distance from the center that the force is being applied, and there is greater torque without increasing your effort. The handle is made to be wide, so that a greater torque can be exerted. It is also much easier to grip a screwdriver than it is to grip a screw. That also plays a factor.

Use a T25 Torx screwdriver on a fine screwdriver shaft down the centre of the drive shaft (in the bottom of the square hole). The screw has a right hand thread. This will allow the clutch cover to come off. You will then need a special spanner with two 3/16" pins, 1" apart anda 5/16 hole between them, to screw off the two clutch counterweights. Again a right hand thread. The finest screwdriver shaft I could buy was "just" too tight and I had to open out the centre of the square, very slightly to allow the s/d shaft to fit in. Good luck. redtag55

What's the advantage of using a long screwdriver?
A long screwdriver is handy when screws are deeply recessed or hard to access (such as in an engine bay reaching through the fan and under the starter motor where big human hands don't reach). A long screwdriver can be easier to keep on the screw head. Picture a driver being held on a screw head in a wobbly hand where the driver stays on the head but the handle is rotating in an arc. Lets say the driver will slip out of the screw head if the hand wobbles more than 10 degrees off square to the screw head. For a long driver, this may need a wobble of 20mm, but the equivalent arc when using a stubby driver might result from only 5mm movement of the handle, needing a steadier hand.
