Milwaukee 12-Piece 3/8″ Drive SAE 12-Point Deep Socket Set 48-22-9421

ENGINEERED FOR MAXIMUM VERSATILITY AND SHOP FLOOR EFFICIENCY

Mechanical efficiency on the jobsite often comes down to the small details that prevent downtime. The Milwaukee 48-22-9421 socket set redefines the standard deep socket with its innovative FOUR FLAT geometry. By squaring off four sides of the socket, Milwaukee has eliminated the common frustration of tools rolling off slanted surfaces or out of reach under heavy machinery. Beyond stability, these flat sides provide a secondary drive surface, allowing for wrench-assisted torque when clearance for a ratchet is restricted. The 12-point design ensures rapid engagement with fasteners, which is critical when working in blind spots or tight engine bays where every degree of swing counts. Finished with high-grade chrome plating and high-visibility laser-etched markings, these sockets are built to withstand the chemical exposure and physical rigors of a professional shop while maintaining long-term readability.

• / FOUR FLAT Sides prevent rolling on uneven surfaces and provide wrench-ready compatibility for high-torque applications.
• / 12-Point socket geometry allows for easier alignment and faster engagement on a wider variety of fastener types.
• / Deep well profile enables access to recessed fasteners and accommodates long threaded rods.
• / Laser-engraved size markings ensure permanent visibility, even after years of heavy use and exposure to grease.
• / Chrome-plated finish provides industry-leading protection against rust and corrosion for maximum tool life.
