What is the use of ring spanner?

A ring spanner, also known as a socket wrench, is a tool used to tighten or loosen nuts and bolts. Its design features a circular opening that fits over the fastener, providing a secure grip and allowing for greater torque application compared to a traditional open-end spanner. Ring spanners come in various sizes and can be used in tight spaces where other tools may not fit. They are commonly employed in automotive, mechanical, and construction applications.
