Metric Bolt Torque Table Nm

Postby Galactic Greyhound » Sun Oct 03, 2010 3:29 pm

Hi folks,

If you use a torque wrench and have ever wondered how much to safely tighten a bolt, or whether the torque setting given in the manual is a typo error then here is a link to a handy printable Metric Bolt Torque Table covering 8.8 Hex head, 10.9 Hex head bolts and 12.9 Socket Head cap Screws:" onclick=";return false;

IMPORTANT These figures are the safe clamping torque for a given bolt before it will break - they are not the torques to be used if the bolt is threaded into anything other than a materially equivalent steel nut or suitably threaded steel hole. If the bolts are threaded into alloy, aluminium or any other less strong material then a lower torque must be used to avoid stripping out the threads - see the manufacturers manual for the appropriate torque values to use.

Thanks to for the data.
