I'm afraid that the metric equivalent of Grunt conversion would involve
calculating fig newton pied du roi (not to be confused with cor du roi),
which I'm unfamiliar with, but I believe is included in the French version
of Machinerys Handbook.

They use it frequently in bicycle design.

Maybe the correct tightening torque would be: not quite a full grunt.

I'm fairly sure that starting at a half of a grunt, then trying a little
more, would do it.

but I wonder if your collets are seating properly.

No collets. I don't use it very often and changing tooling is even
less frequent. A consistent minimum acceptable tightening torque will
solve the problem.

For us in the metric world ,do you have a metric equivalent of 1 grunt?
