Use a striking-face box-end wrench to loosen a frozen nut.
Solución
To determine the best wrench to use when a nut is frozen onto a bolt, let’s analyze the options:
(A) A striking-face box-end wrench: This type of wrench can deliver a strong impact, which can help break the rust or corrosion that may be causing the nut to be frozen. The enclosed design also provides a good grip on the nut.
(B) An open-end wrench: While this can be used, it may not provide as much grip or leverage as a box-end wrench, especially if the nut is very tight.
© A pair of pliers: Pliers can grip the nut, but they may slip and are not designed for high torque applications, making them less effective for frozen nuts.
(D) A crescent wrench: This adjustable wrench can fit various sizes, but it may not provide the same level of grip and torque as a box-end wrench.
Given these considerations, the best option for dealing with a frozen nut is:
(A) a striking-face box-end wrench.
This tool allows for both the necessary torque and the ability to apply impact, which is often required to loosen a frozen nut.

The Deep Dive
A striking-face box-end wrench is your best bet for tackling a frozen nut on a bolt. This tool allows you to apply force directly and can handle the torque needed to break free that stubborn connection. The striking face design also adds a bit of versatility—as you can tap it with a hammer for extra impact.
When using this wrench, make sure to give the nut a good soak with penetrating oil beforehand. This will help loosen up rust or debris, and using an impact tool or gentle taps can further aid in breaking it free. Just be cautious with the amount of force applied—too much can strip the nut or damage the bolt!
