M20 -bolt, what is the torque value

A squirter washer eliminates the need for a torque multiplier and torque wrench on structural A325 bolt connections. The indicator function of a squirter washer tells you that the optimal torque for a particular diameter bolt has been met. The second and even more practical function is so that during a visual inspection of the bolt, should vibration or wear cause the nut or bolt to come loose, the indicators retract into the washer, making inspection of a bolted connection a VISUAL, instead of a labor intensive torque check. These washers are in use in the construction and bridge building industry.
The torque needed to loosen a bolt or joint is often much higher than the torque needed to put the bolt in in the first place. There is no set value difference between the two, unfortunately.
Torque is difficult value to estimate. Especially, for material like stainless steel. There are many factors that effect the value of torque. One of the biggest variable is friction. Since this is almost impossible to control in "field" applications, it is crucial take this into consideration when designing bolt connections.
The first thing we have to know is--what torque? Is it Head bolt torque, rod bolt torque, main cap torque, water bolt torque, or something else? Please specify.

The bolt could have been faulty, or the torque wrench may not be calibrated.
The torque of a water pump bolt can be requested from the manufacturer. The Chevy Trailblazer has a high torque for the water pump bolt.
It is in a shlp manual from AUTOBOOKSONLINE.COM
Torque is not the type of bolt but a type of wrench used to tighten bolts. A torque wrench will tell you how tight a bolt is tightened like 60lb of torque or tighten to 80lb of torque so a bolt will be tight enough to stay in but not too tight that you strip the bolt.
Bolt pre-tension is also called induced load or clamp load. Induced load in the bolt is the load generated in the bolt at a particular torque value. This induced load value is generally 75% of the proof load value. Parveen Lohera Sr. Manager-QA Deepak Fasteners Limited, INDIA
