The socket wrench is best used for loosening or tightening nuts and bolts because it provides a secure fit over the nut or bolt head, allowing for efficient torque application. This tool is designed to work with various sizes of nuts and bolts by using interchangeable socket heads that fit onto the wrench handle.

Using a socket wrench allows for a more controlled application of force, minimizing the risk of stripping the fastener compared to other types of wrenches. Additionally, the design of a socket wrench enables easier access in tight spaces, making it a preferred tool in mechanical and automotive applications where reaching fasteners can be challenging.

While pipe wrenches are specialized tools for gripping and turning cylindrical objects, typically pipes, they are not suitable for use on nuts and bolts due to their design. Adjustable wrenches offer flexibility in size but can slip off if not properly adjusted, which may lead to rounding the edges of fasteners. Torque wrenches are specifically designed to apply a precise level of torque rather than for general loosening and tightening, making them more suited for applications that require specific tension settings. Thus, the socket wrench is the most reliable and versatile for general fastener tasks.
