Torque settings - various

[Tinerfeño]

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 - 105 Nm (90-120 Nm)
• M16 - 180 Nm (160-200 Nm)
• UNC 1/4" - 9 Nm (6,8-9,5 Nm)
• UNF 1/4" - 9 Nm (8,1-12 Nm)
• UNC/UNF 5/16" - 24 Nm (20-27 Nm)
• UNC/UNF 3/8" - 39 Nm (35-43 Nm)
• UNC/UNF 7/16" - 78 Nm (68-88 Nm)
• UNC/UNF 1/2" - 90 Nm (81-102 Nm)
• UNC/UNF 5/8" - 136 Nm (122-149 Nm)

Anyone happen to know the size of the bits required for the diff fill/drain bolts?
