Maybe the secret to potato potato?Yeah squish gaskets stretch threads & bolts then use the RFT torque value (Real Frickin Tight)

Yamaha outboard motors use torque Ft lbs and degrees too for the head boltsCheck out this 5 step process for tightening the head bolts on my Harley M8
Besides using torque valve Harley uses degree value too
Step 5 tighten another 90* turn

144 inch/pounds.One more time the tightness of the nut is how many inch pounds thank you!!!
Ahh, the good ol' angular torque method. It's actually more repeatable and accurate than torque values as things like oil, thread locking compound, grit, etc can actually throw off the actual applied torque value to the bolt because the coefficient of friction between the threads is changed. 50ft-lbs on a dry bolt can easily be double that applied to an oiled bolt, but the torque wrench will only register 50. I see lots of people snap small bolts because of this.Check out this 5 step process for tightening the head bolts on my Harley M8

This is why I tell idiots at work to clean and oil the threads and collars of flange lug-nuts as per procedure.Ahh, the good ol' angular torque method.

My favorite one to date is the lower case bolts for the main bearing journals on my honda's V4. 20ft-lbs, followed by 270 degrees done in 3 stages of 90. So glad I spend the money on a fancy digital torque wrench with an angle tracking function and multiple memory points.
You have it there, the difference between oiled, and dry galling situations. Can't say enough about the thumb on the front of the racket and wrist pressure only. Many have mentioned this before, but until you trash a couple and learn the feel for it, now you understand. Just go easy on them and check often.Ahh, the good ol' angular torque method.
