A socket set with a -inch square drive and metric-sized sockets is a common tool collection used for fastening or loosening nuts and bolts. The “-inch drive” refers to the size of the square recess in each socket, which fits onto a corresponding square protrusion on a ratchet, extension bar, or other drive tool. “Metric” indicates that the sockets are designed to fit fasteners with metric measurements, such as millimeters, rather than imperial measurements like inches. A typical collection includes a range of socket sizes, facilitating work on various fastener sizes.
This specific type of socket set balances versatility and strength. Smaller drive sizes, like -inch, are suitable for lighter applications but lack the robustness needed for higher torque. Larger drive sizes, like -inch, offer more power but can be cumbersome for smaller fasteners. The -inch drive thus finds a sweet spot for general mechanical work, automotive repairs, and DIY projects. The widespread adoption of the metric system globally makes metric-sized sockets indispensable for modern equipment and machinery.
