Built to move, the 30 piece Max Axess 1/4 3/8 inch drive set loads into a tight-sealing, blow molded case that wards off moisture and stays organized no matter where duty calls. Built from rugged alloyed steel, each piece in this set stands up to tough conditions, while it?s unique pass-through design keeps you working even when you run into peaked bolts and threaded rod. Ready to adapt, both 1/4 and 3/8 inch sockets in the Max Axess set work with the ergonomically designed ratchet and nut driver, so whether you need serious torque or just rapid spinning, you can quickly get your project together. And since this uniquely designed system has a thinner profile than traditional socket sets, it makes working under tight engines, in cramped spaces below sinks and reaching around appliances, much easier. A solid addition to your arsenal, that packs neat and fast, get to work with this pass through socket system and get results.
