100 nm without a torque wrench

Good rule of thumb finger tight then one flat on the nut and for extra security apply a touch of Loctite Blue before assembly.

You are obviously joking for 100Nm?
Unless you have fingers like "The Thing" from The Fantastic Four?

seriously now, they're 8 or 10mm thread, just lean on them. common sense will tell you if they're tight. (from someone else on here)

The rear axle nut is 150nm , I don't have a torque wrench that goes to 150nm so all I have done with that is mark the flat of the nut and the area next to the nut, Back it off do what I need to do and tighten it back to were it was. All I am using is a split ring spanner no bars or anything else and I am not popping a vein to slacken/tighten the nut. Now perhaps it has not been torqued up to the correct torque in the first place , but guess what the wheel has never come off or come lose on me yet. All I am doing from finger tight is turning the nut through 1.5 flats
After spending my working life as an engineer I reckon I would have a pretty good idea when a nut is tight.

So how many flats do you reckon from finger tight on a 8-10mm bolt/nut do you reckon you would need to turn it to achieve 100 nm?
