A socket set with a -inch square drive utilizes interchangeable sockets designed for high-torque applications, commonly found in heavy machinery, automotive repair, and industrial settings. The “metric” designation specifies that the sockets are calibrated for use with fasteners measured in millimeters, adhering to international standards.
This specific tooling configuration provides substantial mechanical advantage for loosening and tightening large fasteners, crucial for tasks involving significant force. Its widespread adoption stems from the global standardization of metric measurements, enabling interoperability and simplifying tool selection for diverse applications. Historically, the transition to metric systems in many industries necessitated robust tooling solutions, leading to the development and proliferation of such drive systems.
