DeWalt 21 mm x 3/8 in. drive Metric 6 Point Deep Socket is built for durability and precision in demanding jobs. Forged from chrome vanadium alloy steel, this deep socket delivers lasting strength when you’re working with metric fasteners in tight spaces.
The 6-point design provides a secure grip on hex heads, helping to minimize rounding and slippage under torque. Paired with a deep socket profile, it reaches recessed fasteners and bolts that sit beyond the reach of standard sockets—making it a reliable choice for engines, machinery, and equipment where space is limited.
The polished chrome finish not only looks fast and professional but also resists corrosion and cleans up with ease after tough jobs. With a 21 mm metric size and a 3/8 in. drive, it’s perfectly matched to common metric fasteners used in automotive, cycling, and home repair projects. This is a non-impact socket, designed for use with standard ratchets and extensions in everyday manual tasks.
What you get: 1 socket in carded packaging, designed for single-use convenience and easy storage in your toolbox.
