If I cannot find the INEOS nominated torque, I look at general torque values like this:
When angle torque values are found a note "Renew bolt" should be added because these are tightened over the yield strength. Re-use will break or at least stretch the bolt and correct force on the joint will not be achieved.
I have decades used following general torque values for 8.8 bolts and 8 nuts if nothing else is available. Take care when use these.

- M5 - 6 Nm (5-7 Nm)
- M6 - 9 Nm (7-10 Nm)
- M8 - 25 Nm (22-28 Nm)
- M10 - 45 Nm (40-50 Nm)
- M12 - 90 Nm (80-100 Nm)
- M14 -...
