The STEELMAN 78521 1/4-Inch Drive Deep Well Metric Socket Set provides you with nine high-quality, chrome-vanadium steel sockets. The heat-treated satin finish provides a non-slip surface that is a saving grace when you’re working with greasy hands, and the included clip-on storage rail is ideal for keeping your workspace more organized. The thin-walled design allows these sockets to access fasteners in confined spaces. The set includes the following 6-point sockets: 6, 7, 8, 9, 10, 11, 12, 13, and 14mm. To make identifying the sizes easy the size callouts have been laser-etched onto the side of the sockets in easy to read letters.
