The 142-piece mechanic tool set from DeWalt includes two pear-head ratchets, a variety of sockets, extensions, universal joints, and adapters, all housed in a sturdy case with metal latches for added security. The 72-tooth ratchets are equipped with a quick-release mechanism for easy attachment and removal of sockets. The sockets feature DirectTorque technology, which prevents rounding of fasteners and provides better grip.
