How would you do it?
Here's an old mechanic's trick:
|Start with a piece of tape perhaps an inch long, |
held sticky side up
|Push the screw thru the tape, |
so that the sticky side is against the
underside of the screw head
|Insert the screwdriver into it's recess on the screw|
head, and fold the two flaps of tape up over the
head onto the blade of the screwdriver
* I meant that to be parsed as an old trick that mechanics know, but I suppose it could also be a trick that old mechanics know...
