Which is about 103 ft·lb. I round to 100 with torque stick then I follow up with torque wrench after driving a bit usually 50-100 miles.
This is an example of grossly over torqued BMW lug bolt.
M14-1.5 10.9 bolt standard torque is 202 N·m. So the 140 has a safety factor against stretch of 44%, however it's very easy with power tools to go over that number (as evidenced by the bolt I'm holding above). Do not ever "ugga dugga" without a torque stick!
