For maximum efficiency, our ratchet and socket set includes sockets with FOUR FLATTM Sides, which prevent rolling, and wrench compatibility. The 90-tooth ratchet tool with a small profile and 4° of arc swing allows for operation in confined locations. For easier reading, we have stamped the sizes into each socket. Both the SAE & Metric 56-piece 3/8" and 50-piece 14" Drive Ratchet and Socket Sets can be kept organized in the provided PACKOUTTM Low-Profile Organizer, which has a clear top for quick part identification. With a reinforced hinge and strong latches, this PACKOUTTM Organizer is IP65 rated and made of impact-resistant materials for durability on and off the workplace. A component of the MILWAUKEE® PACKOUTTM Modular Storage System is the Compact Low-Profile Organizer.
