Hmmm, With regard to drain plugs...I never really thought about it before, but a steel drain plug fitting a steel pan is ?3/4" or ?14mm, or ?9/16" hex head? Anyway, the shank is acutally quite large. But I would not look on a torque table for a setting as I think it might overkill. If most plugs take crush washers it would seem the "first"application would flatten the copper washer and subsequent ones would apply more torque to mate the work hardened washer to the pan. Perhaps (my bad) I do keep using the same flattened washer so the snug torque is higher than any manual callout which may require "always replace." I have had more problem with others' overtightened sump plugs than any of my moderately tightened ones. The motor mounts inhibit vibration loosening. I guess stay with any callout you find in a manual, otherwise experience and judgement. I have found the H Frt "fish tackle box" of copper washers to work well if they fit as drain washers and also brake line/caliper washers.
