We are setting up some heavy-duty temporary steel shoring for a commercial bridge repair project. The engineering plans specifically call for Hot-Dip Galvanized "Heavy Hex" bolts for all the primary load-bearing flange connections.
We have plenty of standard HDG hex bolts in the exact same grade and length. For a temporary structure that will only be up for 8 months, does the wider head of the Heavy Hex really make that much of a structural difference? Will standard hex heads pull through the steel under heavy vibration?
