After reading the woes of sheared nuts/studs, I took to removing all of my Tuner Nuts to apply a thin layer of Coppercrest to the threads to reduce the likelihood of cold welding. I also dropped the tightening torque down from the (Bola) recommended setting of 130 to 127Nm as my (800Nm) Impact Wrench struggled to remove at least 3 of the nuts which had been over-tightened!

Another discovery was that I have an ‘odd’ nut that is shorter than all of the others (32mm vs 37mm). OCD triggered! Email to Skidz has been fired off for a new nut.
Hopefully I’ve saved myself some trauma down the line (thanks to this thread).
