Milwaukee 3/8" Drive 21MM Metric 6-Point Deep Well Socket 45-34-8041

ANTI-ROLL PRECISION FASTENING DOMINANCE

Engineered to redefine the standard of mechanic's hand tools, the Milwaukee 45-34-8041 3/8" Drive 21MM Deep Well Socket integrates the innovative FOUR FLAT™ geometry. This isn't just a socket; it's a solution to the frustration of rolling tools and the limitations of traditional round profiles. By providing parallel flat surfaces, Milwaukee allows users to apply additional leverage via a wrench while ensuring the socket stays exactly where you set it on the bench. The internal 6-point architecture is precision-machined to grip the flats of fasteners rather than the points, significantly extending the life of your hardware and reducing downtime caused by rounded bolts.

• / FOUR FLAT™ Sides provide an anti-roll solution and wrench-ready surfaces for maximum torque versatility.
• / Optimized 6-point geometry protects fasteners from stripping and rounding under high-load applications.
• / Deep well construction enables access to recessed fasteners and clearance for long threaded bolts.
• / Stamped metric sizing into the flats ensures long-term visibility and quick identification in crowded tool chests.
• / Chrome finish provides superior corrosion resistance and easy cleanup after heavy-duty service cycles.
