Not to hijack the thread, but maybe a few words on torque specs would be appropriate:
Torque specifications aren't set to protect the parts being held together from excessive compression. Torque specs are designed to prevent exceeding the elastic limit of the material the threaded fasteners are made of. It's the elasticity in the steel of the screws, bolts, lugs, whatever, that provides the tension that keeps things tight. If, by over torqueing, you apply sufficient tensile stress to exceed the elastic limit of the fastener material (not hard to do if you calculate the mechanical advantage derived from screw threads) there is nothing to hold the fastener tight except friction.
