That strikes me as the reification of what's pretty clearly a social difference. More men than women know what a torque wrench is, because we teach boys about torque wrenches and let boys know that they ought to know what one is, while we teach girls about other things and let them know that it's okay to be ignorant about torque wrenches.
When I was a kid there was a common party game where the boys and girls would break up into separate teams, and the boys would attempt to come up with questions that they could all answer but would stump all the girls, and the girls would do the same to the boys. It was, at least that I ever saw, always much easier for the girls to come up with questions that would stump us guys than for us to come up with "common guy knowledge" that would stump all the girls. There were always more girls who knew "guy things" than guys who knew (or were willing to admit to knowing) "girl things."
I'm not sure that really proves anything except there was a wider diversity (at least within the relatively limited sample of kids I grew up with) of acceptable gender role behaviors for girls than for boys. Girls certainly can know "guy stuff" when they're exposed to it, that much was pretty obviously clear.
It may be that there's some biological difference between how men and women approach problems, or learn various skills. But I can guarantee you that those differences are, like differences associated with skin color, far less than the differences between individuals in the same group.
