a bunch of those bolts are the same length but if you are sourcing locally or online you may bot know the length needed unless you have a sample. the length of a bolt is measured from the under side of the head down to the end of the threaded part. just do a quick measure and see how long they need to be. if they are a little long it will likely be ok since they have threads up to the top. too short will suck.
some flange head bolts are smooth under the head and some are serrated. serrated holds them tight but removes paint as the bolt is tightened. same goes for the ones with the washer that spins freely.
