What is a key advantage of an open-end wrench?

It can be used in tight spaces
It can engage fasteners from the side
It is adjustable for different sizes
It requires less force to tighten

The correct answer is: It can engage fasteners from the side

The key advantage of an open-end wrench lies in its ability to engage fasteners from the side, making it particularly useful in situations where a straight-on approach is not feasible. The design of an open-end wrench features two prongs that fit around the flat sides of a nut or bolt, allowing the user to apply torque effectively without the need for direct alignment. This side engagement is beneficial for accessing fasteners in tighter areas, such as when they are blocked by surrounding structures or other components. While open-end wrenches do offer some advantages in close quarters, options related to space limitations or adjustability apply more closely to specific types of tools like box-end or adjustable wrenches. In contrast, the ability to engage fasteners side-on remains a definitive trait of open-end wrenches, enhancing the versatility and usability of these tools in various applications.
