This 157-piece set includes a spread of screwdrivers, ratchets, 1/4" sockets and more. Sonic screwdrivers are built with ergonomic tri-lobe plastic handles and a rubber over-mold for comfort and grip. Chrome Vanadium shafts ensure durability for years of use, and a hardened tip offers maximum gripping power. This set includes Hex-key and Torx-key sets, which come with a plastic folding case to keep everything tidy. In the Sonic Foam System, tools are better organized, quickly accessible for fast workability, ergonomically laid out, and feature a two-tone color system for convenient survey of missing tools.
