Spent some time gatherings parts (bits, cutting oil, torch) and it s been tons of rain here and temps now dropping to sub zero. My broken bolt removal task is pending some help from Mother Nature. Meanwhile I spent some time today with steel wool and got the broken bolt cleaned up a bit and there is in fact a "7" stamped in the middle of the hex head. I’m revisiting the manuals as this may be mentioned in the torque tables somewhere. I’m posting here in case it rings a bell for someone?
Edit: the service manual has a torque chart showing range of 116-137 ft lb for M16 bolts with a “7” marking. Does this seem a bit low for a grade 10.9 bolt? Mostly curious. I’m actually hoping these old bolts are a lower grade so I’m not out there drilling all day.
