There are published values in engineering handbooks for tightening torque with and without lubrication. With lubricant the torque value will always be lower. I sheared the threads clean off the shock mounting bolt on my YZ250 when I put Mobil 1 synthetic grease on the threads - and I was torqueing it to the published value with a calibrated torque wrench.
