The MILWAUKEE® 3/8" Drive Triple Square Bit Sockets with FOUR FLAT™ sides are designed from the ground up to be part of the most versatile socket family. Milwaukee® sockets feature an innovative design with four parallel flat sides, which deter rolling and are wrench compatible. This also creates a slim profile to provide the best access in tight spaces. The one-piece socket 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. All Milwaukee® sockets are backed by a Lifetime Guarantee.
