Does heat shrink or expand metal?
The expansion (or contraction) of any material is due to the kinetic energy of its atoms. When a material is heated, the increase in energy causes the atoms and molecules to move more and to take up more space— that is, to expand. This is true of even a solid such as a metal.
Does heating up metal weaken it?
It’s often used to create steel that is stronger than annealing the metal, but also creates a less ductile product. So, heat can indeed make metal weaker.

How does a ratchet wrench work?
A ratcheting wrench works virtually identical to a socket wrench – it has ratcheting pawls inside that lets it spin in one direction and turn the bolt in the other. Instead of having one drive that fits a bunch of different sizes, each ratcheting wrench is a specific diameter.
