The TOLSEN 15139 is a 22-piece socket set designed for automotive and industrial fastening tasks, specifically for mounting and dismounting threaded and end connections. Built from chrome vanadium steel, the kit includes 15 metric sockets ranging from 10 to 32 mm, along with two spark plug sockets in 16 mm and 21 mm sizes to handle engine maintenance. To make working in tight spaces easier, the set features a 72-tooth ratchet with an ergonomic two-component handle and a quick-release mechanism, complemented by a universal joint and a three-way adaptor. You can extend your reach using the 125 mm and 250 mm extension bars, while the blow mould plastic case keeps everything organized and portable for transport between jobs.
