[RE-wrenches] Over-torquing Module Clamps?

[Jeremy Coxon]

That particular racking system is not very forgiving of over torquing because the SS studs are embedded in aluminum.  I have seen where the stufs for both the mod clamps and the wind deflectors just spin in the aluminum.  We use socket wrenches and torque wrenches to avoid that failure mode, especially on Ecolibrium.   It takes FOREVER to try to remove a nut from a galded SS stud that you can’t grip.  So the extra time of going manual is made up of just one or two nuts get stuck or a stud spins.
