The Tolsen 15144 is a comprehensive 108-piece socket set designed to handle a wide variety of mechanical tasks using both 1/2" and 1/4" drive sizes. It includes a broad range of standard metric sockets from 10 to 32mm for the larger drive and 4 to 14mm for the smaller one, complemented by deep sockets and star metric options to reach recessed bolts. For specialized work, you will find spark plug sockets in 16 and 21mm, as well as a versatile selection of Cr-V and S2 material bits covering Phillips, Pozidriv, Slotted, Torx, and Hex profiles. To help you reach tight or awkward spaces, the set comes with extension bars in various lengths, universal joints for both drive sizes, and a 3-way adaptor. The tools are managed by two ratchets and a 1/4" socket handle, while three small hex keys provide additional utility for precision adjustments. Everything is organized within a durable blow mould case, which keeps the components secure and makes the entire kit easy to transport between different workspaces.
