Wax has some unusual properties.
When I experimented with torque on scope mount screws, I ran into the wax question.
If there are enough threads engauged, the threads do not strip, the screw breaks.
Different screws made of different metal have different yield tensions.
But wait. There's more.
Knowing a screw max tension does not tell a screw's max torque. Some torque is lost to friction.
So it looks something like this:
Max torque for that screw :
34 inch pounds dry
28 inch pounds with oil or grease
16 inch pounds with Johnson's paste wax
Another odd thing is that it does not break down in sunlight.
I put a new board on a deck as a rail and painted it, and thinly rubbed a layer of Johnson's wax on a small section.
Two years later the water was still beading up on the wax section.
There is not just wax in that can. There is some solvent in there too, with a high vapor pressure. The wife will smell that stuff and protest. Or wait a couple days before you bring the project in the house.
