Torque and bolts

Hi list,

According to ARP the friction (which leads to the torque reading) of any 
given fastener is highest the first time it is used and progressively 
decreases to the point where it no longer drops because the friction levels 
out and becomes constant.  Thus ARP recommend that new fasteners should be 
tightened and loosened through FIVE times before final torque is applied.
