That has also worked for me too bigted and havn't had one shatter either of that size so far , but protective eye wear is a Must. The rattle gun I have has 4 settings and I set that to the highest setting which is number 4 on my cheap set, but firstly set on 2 to try and bed the socket first to avoid slipping. Sometimes tapping the socket on first if the bolt has been tampered with beforehand helps.
