A socket set is a versatile and convenient bundle of toolkit accessories that gives users the flexibility to tackle multiple sizes and types of fasteners, primarily aimed at fitting to a diverse range of nuts and bolts. Socket sets are usually packaged as a single handy case, box or pouch of numerous interchangeable attachments. When tackling especially tough or rusted fasteners, having a well-stocked socket set on hand usually gives users the ability to select a socket with a close-to-perfect fit over or into the nut or bolt head.
