Yes it is. When you torque you need to stop as the bolt is moving - that is dynamic torque. When you are checking the torque (bolt6 is not moving)that is static torque which can be 10 to 20% higher than the dynamic torque in my experience.

That means that in order to move a bolt after it has been torqued it can take 10 to 20% more torque to move than it did on the initial torque.

In your case that means you were below 35 lbs if the beam torque wrench is accurate.

I do a lot of work with torquing bolts.........
