I recall from AISC edition 7 that the preferred method of tightening
structural bolts for bearing connections was the turn-of-nut method.
Looking at ASD and LRFD current editions, the method for bearing connections
is called snug tight. I prefer the turn-of-nut method and wonder if this
requirement is an undue expense for the erector. Does anyone have a feel
for the cost difference????
