What is the proper usage guideline for wrenches?

The proper usage guideline for wrenches emphasizes that they should not be used as a hammer. Wrenches are precision tools designed to grip and turn bolts and nuts, and using them to strike objects can damage the tool itself, weaken its structure, or compromise its effectiveness. Additionally, using a wrench as a hammer could lead to injuries, as it is not designed for impact.

When wrenches are used appropriately, they allow for proper torque application and are less likely to slip or cause damage to fasteners. This ensures not only the integrity of both the tool and the fastened components but also the safety of the user. Misusing tools like wrenches can introduce hazards, so adhering to the guideline of never using them as a hammer is crucial for safe and effective use.
