Oh I forgot to mention: broke a 27mm socket and a 3/4 to 1/2 adapter and a 1/2" drive ratchet (when I thought I had loosened the bolt a bit) all before I replaced the broken 1/2" drive socket with a 3/4" drive. This was on an M62 motor with clearly a bigger bolt (I believe the bolt is 18mm with 27mm head).
