Idler Pulley

2001 XJ 4.0L here. What is the bolt that goes through the center of the idler pulley for? It seems like you would just turn the adjustment screw to vary the tension on the pulley, and not mess with the bolt. Does it actually hold the idler pulley in place, or does it just lock it down after adjustment?
 
Center screw tightens pulley down
 
if you do not tighten down the center nut of the ideler pully over time it will creep out of ajustment causing ssssssccccwwwwwweeeeellllliiiiiiinnnnnngg and most probably your belt will fly off at the worst posible time.
