I know it's not exactly what you're asking, but I'd suggest just "nipping it up", or "engineers feel" as you describe it will be fine.
The torque setting is not a lot, it's basically just a little beyond hand tight.
I did my oil change last week and was pretty gentle with it because I'm always terrified of stripping threads.
I've always been advised to just do it up until it starts to resist, then just a little tiny bit more and done. I've never had a problem with it coming undone.
But if you prefer, perhaps someone else may be able to suggest a say to get your torque wrench in.
PS) Welcome on board!
Oh one final tip, if you mark the bolt and the casing with nail varnish or a wax marker or similar and check it every now and again then you'll be able to see any movement. Nice tip I got from Delboy's garage on youtube.
