SUMMARY

The discussion clarifies the application of torque when using a screwdriver or nut driver to loosen or tighten nuts and screws. It establishes that a screwdriver is primarily used for screws, while a nut driver, which resembles a screwdriver, is specifically designed for nuts. The key distinction lies in the application of torque at the head or tip of the tool, which is crucial for effective fastening. Understanding this difference is essential for proper tool usage in mechanical tasks.

I think one loosens or tightens a screw with a screwdriver, while one uses a wrench or nut driver (looks similar to a screwdriver) to loosen or tighten a nut.

What is significant between the tip of the screwdriver (or nut driver) and the handle?

One is applying a torque at the head/tip.
