Does anyone know recommended tightening values (tension and/or torque) for a
3" dia A449 anchor bolts? Most references list snug tight values to 1-1/2"
dia bolts, and state that "snug tight" is not less than 15% of yield.
However, for an anchor bolt just getting to this theoretical snug tight
value seems incredibly large. Any recommendations/references?
