Backing them off a half turn provides a little clearance and ensures the stresses are only on the threaded areas as designed for the original bolts which would of course never bottom out. KKROFFT Now occurs everywhere, simultaneously. But it doesn't have to be experienced the moment it happens.   Every now that ever was is still exactly when it was, when it was now.   Then, in terms of perception, is nothing more than all the nows that are no longer now.   Thus, the difference between now and then is when.    --The Waystoppers Users' Manual
