Our 106pc 1/4 ", 3/8", and 1/2" Drive Bit Socket Set features sockets with FOUR FLAT™ Sides that deter rolling and are wrench compatible for maximum productivity, making them a part of the most versatile socket family. The one-piece design offers improved durability compared to two-piece designs by eliminating the risk of the bit separating from the socket base. The laser-engraved size markings provide easy identification, and chrome plating offers rust and corrosion protection. The bit sockets and socket adapters are arranged in a removable storage tray inside a PACKOUT™ Organizer, which is equipped with a clear top for easy identification of parts at a glance. The Organizer is part of the MILWAUKEE® PACKOUT™ Modular Storage System, which is the most versatile and durable in the industry. A Limited Lifetime warranty covers the PACKOUT™ Organizer, while a Lifetime Guarantee backs the bit sockets and socket adapters.
