I might not be a RL car mechanic, but I do make a living of wrenching stuff for the oil industry and I am certified to use both manual and hydraulic torque tools.
You must be doing something wrong to shear those ARP straight off.
They might all be damaged (stretched) if you have over tightened them past the tensile strength of the material.

There are ways to check for damage.
-Measure the studs OD in various places, they are damaged if they are shaped like a woman.


-You can also measure the thread pitch, the studs are M12x1,25.
That means that 10 threads should be 1,25cm, 20threads 2,5cm and so on.

What sort of nuts are you using? Quality or cheap chinese ones?
If might be the nuts causing this as well, a bad material combo can do that.
Are the nuts seizing and shearing when you try to un-sqrew them?
