CMMT44447 21mm 12-Point Deep Socket, 1/2 In. Drive

The Craftsman CMMT44447 21mm 12-point deep socket is engineered for precision fastening work where access is tight and durability matters. This metric socket features a 1/2-inch drive that connects with most standard ratchets and impact tools, making it a versatile addition to any mechanic's, technician's, or serious DIYer's toolkit. The extended length of a deep socket reaches bolts hidden deep within engine bays, machinery, and tight assembly spaces, reducing the need to swap between multiple tools.

Built from high-strength alloy steel with a polished chrome finish, this socket resists corrosion while delivering a professional appearance. The 12-point design grips fasteners with twice the contact points of a 6-point socket, enhancing torque transfer and minimizing the risk of rounding off bolt corners—a common problem that can ruin fasteners and waste time on repairs.

Features and Benefits

• 12-Point Contact: Double the grip of a 6-point socket prevents cam-out and bolt rounding, ensuring reliable fastening on automotive, industrial, and assembly tasks.
• Metric 21mm Size: Matches standard metric fasteners precisely, streamlining your work without guesswork or incorrect sizing.
• Extended Reach: The deep socket design reaches bolts hidden deep within machinery and engine compartments, reducing the need to swap tools.
• Alloy Steel Construction: Engineered for superior strength and wear resistance, this socket handles demanding automotive and industrial applications.
• Polished Chrome Finish: The protective coating shields the tool from rust and corrosion while maintaining a clean, professional look.
• 1/2 Inch Drive Compatibility: Works seamlessly with most ratchets, torque wrenches, and impact tools for versatile use across multiple projects.
