Hello Matt,

You probably will not find this listed. It is not critical, standard metric hardware grade 8.8, I believe. It doesn't take a lot of torque to seal the rubber o ring here. Just be careful not to break them off. Use a generic metric hardware torque table if you are not comfortable with the "feel technique".

Hello Matt,

Here is a chart for standard SAE and Metric hardware.

 Remember your bolt size is actually the diameter or the bolt shaft not the head size! The 10mm head bolt you are dealing with is actually a 6mm bolt size.

Joe,
I am looking for the torque to mount the housing to the case not the top of the housing when replacing the thermostat.

I tightened it up to what "felt" snug.  Just want to avoid any leaks.

thanks
