Mechanical engineers refer to the "turn of the screw" method for 
tightening.  With a little practice one easily notices when the force 
required to turn the screwdriver further begins to ramp up more 
quickly.  [This point is past "finger tight", which often doesn't 
compress the lockwasher very much (if at all).]

When that ramp-up starts, go one-quarter turn further to reach the 
design load point.

This also works on the big bolts used on bridges and other ironwork.
