Just tried to fit up an oil temperature sensor to the oil filter drain plug. Its M10x1mm. Its not tapered and I fitted with copper washer and thread tape. Fitted well, but I tightened to what I thought was enough to stop an oil leak but it sheared off. As its a thin hollow tube, then torque is less than a normal brass bolt. No details came with it. Some sites suggest for 8Nm to 18Nm. All over the place. Does anyone have an idea what sort of torque I should be looking at. I don't expect the exact value, just that I don't have a feel for what sort of value to use on a thin hollow brass tube.
