The Husky 605-Piece Master Mechanics Tool Set is the ultimate set for professional and DIY mechanics alike. This massive set contains almost every hand tool needed to work on vehicles, machinery, and equipment.

The centerpiece of this toolbox-sized set is the wide assortment of sockets and drive tools. 7 ratchets in the most commonly used drive sizes provide the ability to turn and tighten fasteners in tight spaces. A whopping 333 sockets in both 6-point and 12-point configurations allow you to find the right socket for hex bolts, spark plugs, oil drain plugs, screws, and more. Deep, standard, and specialty sockets ensure you have the right socket for the job.

Beyond the sockets, this set includes a full spectrum of other essential mechanics tools: 100 combination wrenches provide both box-end and open-end options for all socket sizes. 55 hex (Allen) key sets handle set screws and machinery fasteners. 11 screwdrivers, including Phillips and flat tip, give versatile options for those standard screw types. 19 extensions and adapters extend your ratchet reach or convert drive sizes when needed.

Every tool here features excellent attention to detail from Husky. Ratchets have fine-tooth engagement for tight spot access yet can quickly zip off fasteners when space allows. Sockets have chamfered lead-ins to easily fit fasteners. Markings are clear and durable. The polished chrome and black oxide finishes offer protection and easy cleaning. Plus, the set comes backed by Handyman Club of America’s lifetime replacement guarantee to cover you if anything ever fails.

With 605 total pieces covering virtually any fastener or bolt you’ll encounter in vehicles, machinery, equipment and more, the Husky Master Mechanics Tool Set will make an excellent investment for anyone from professional mechanics to DIY hobbyists.
