Engineered for strength and access, the DeWalt 18 mm 3/8 in. drive metric 12-point deep socket is a trusted tool for mechanic work, automotive maintenance, and shop tasks where recessed fasteners demand a longer reach.
Made from chrome vanadium alloy steel and finished with a robust chrome plating, this deep socket resists rust and stands up to daily use. It is metric (18 mm) and designed for 3/8" drive ratchets, offering a reliable fit and smooth operation.
Key design features that matter in the real world
-
12-point geometry: Provides multiple contact points for fastener engagement, making it easier to align and reduce the risk of rounding in tight spaces.
-
Deep reach (2-7/32 in length): Extends past shallow sockets to access recessed hardware, extending versatility across engines, chassis, and machinery.
-
Solid compatibility: 3/8" drive suits standard ratchets and extensions and works with common 18 mm bolts found in many European and Asian vehicles.
-
Precise dimensions for fit: Nut end and drive end outside diameter both 15/16 in., nut depth 25/32 in., bolt clearance depth 1-9/16 in.—these specs help ensure a reliable bite on stubborn fasteners and clearances in compact spaces.
-
Quality construction: Chrome-plated finish protects against corrosion and stands up to shop use; not designed for impact-rated use, so pair with a hand-operated ratchet for longevity.
-
Packaging: Carded packaging keeps the tool protected and easy to shop for in hardware aisles.
Who benefits most? This 18 mm deep socket is ideal for automotive technicians, DIY mechanics, and equipment technicians who regularly encounter recessed 18 mm fasteners in engines, wheel hubs, brake calipers, and subframes. It’s also a practical addition for cabinetry or machinery projects where space is tight and fastener access is limited.
Why choose this DeWalt socket over other options? The 12-point design minimizes fuss when starting a bolt in low-light or awkward angles, while the deep socket format gives you the extra reach required for clearance around hoses, pipes, and components. The chrome-vanadium alloy with chrome plating delivers a durable surface that resists wear and corrosion, ensuring this tool remains a staple in your toolkit for years.
Practical tips for best results:
- Use with a standard 3/8" drive ratchet or extension to maximize reach.
- Avoid using impact drivers or high-torque impacts with this non-impact-rated socket.
- Periodically wipe and lightly oil the drive end to reduce rust and ensure smooth operation in tight spaces.
