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. on 09 Feb 19 15:20 K9ZTV said the following: > I was always taught the rule is . . .
