</font><font color="blue" class="small">( I have been wondering about that too, concerning possible damage to the joint or stripping the thread. I put my foot on the back tire and put some real torque on mine. After wards I started to think about this. How tight is too tight?? /forums/images/graemlins/confused.gif )</font>
I've attached a torque chart for standard SAE hardware bolts. Note two things:
(1) Values above the line for small bolts are in inch-pounds not foot-pounds and
(2) Lock nuts are to be torqued at 65% of these values per the footnote on the chart
