Setting it at 9 foot pounds may have not been enough to make an audible click. Some torque wrenches will barely do anything at all when set at the extreme low of the scale.
You would have probably been better off using an inch pound torque wrench and then set it to 108 inch pounds, which is equal to 9 foot pounds.
Too late now. But that's probably why they stripped out and/or snapped.
If these screws are just holding the oil pan on, they don't need to be super tight. Your hondabond gasket compound should be fine unless the oil pan got moved around before it dried.
