411/412/603 wheel nut torque?

[Kenneth Andrén]

Hi,

I have lost wheels twice over the last 60 years, apart from my pedal car and "three wheel bicycle", and both times I lost the nuts holding the bolt-on hub extensions for the wire wheels. Both LH rear wheels...any pattern apart from uneven wire wheels? I was doing 70-80 kph

The 'hand tight' explains why different sizes of spanner are different
lenghts, to compensate for average human force applied.
In many cases wheel nuts coming loose can be attributed to other factors,
namely dirty threads, burrs on the nating surfaces[of nut and wheel and
wheel and axle.
Take the time to clean and inspect all mating surfaces, apply a LITTLE
grease to the stud and tighten with the supplied spanner. I would further
recommend that the nuts be rechecked after a few, say ten, miles.
It works for me.
regards,
David
