Bolt Inspection via 'Pinging' 6

[pattimelt]

I saw something that I am not sure I have ever seen on an A325 bolt - a fellow inspector had a small (thumb size) brass hammer and went around to the A325 bolts (3/4") and hit them with this little hammer. Now, I am familiar with this method when you are using a castle bolt and Texas hot rod on something like an intercept valve, but on a structural connection? I didn't want to ask him, so I am asking here - what purpose does this serve? The bolts are installed with a DTI to the nut and inspection is both visual for the 'squirt' and with the .005 gauge.

So, Patti... what did you decide? Will we ever see you out with a brass hammer (or any type of hammer) on a jobsite?
