But that's the whole stupid &^%$()#_ problem!! "Hand tight" is way
too loose of a spec when it really matters. And even when it doesn't.
One person's "hand tight" is another person's "Who put this on here,
a gorilla?" or a third's "it was just about to fall off". ;-P
The hand strength and the leverage access of the person to the
wrench is one huge variable, how far out on the wrench they are
gripping (how much leverage multiplication), and if they are using a
socket and extension, if they're using one hand or two to turn it.
For an oil plug, I'd make my "hand tight" with no more than four or
five inches of leverage on the wrench, or using a socket wrench
one-handed - one finger on the fastener as a guide, and when it stops
turning easily with moderate pressure from two fingers, stop. But I
do stuff like that on a regular basis.
For people who don't turn wrenches regularly, and therefore they
have no practical experience with "How tight is tight enough" on
certain things, they really need to buy and use a good torque wrench
on everything until they get used to how much force is needed - and
always use it for critical items like lug nuts and head bolts.
The Microtork style "Clicker" wrenches (where you dial in the
desired setting in a window) are best, because unlike beam style
torque wrenches they're hard to misinterpret.
