TecoTek 10Pcs 3/8-Inch Drive Extra Deep Metric Socket Set, 6-Point, 8mm–17mm, 120mm Deep CR-V

Overview

Designed for both professional shops and dedicated DIYers, the TecoTek 10-Piece 3/8-inch Drive Extra Deep Metric Socket Set delivers reliability where space is tight and access is limited. Forged from premium heat-treated chrome vanadium steel and finished with a corrosion-resistant mirror polish, these sockets resist wear in demanding environments. Each piece measures 120 mm in length, providing the extra reach needed to access stubborn nuts and threaded studs in crowded engine bays or machinery housings. The result is a tool set that combines strength, precision, and a clean appearance that stays visible on the workbench.

To guard fasteners against rounding under torque, the set uses a six-point design. This configuration concentrates force on the flats of the fastener rather than the corners, helping to maintain grip when dealing with stubborn hardware. The absence of skipped sizes means you always have the exact size you need from 8 mm through 17 mm, reducing the time wasted searching for the right socket.

Key benefits

• Premium construction: heat-treated chrome vanadium steel for durability
• Mirror-polish finish: corrosion resistance and easy cleanup
• Extra-deep length: 120 mm reach for hard-to-get fasteners
• Six-point design: better grip and reduced rounded corners
• No skipped sizes: full 8 mm to 17 mm coverage

Practical uses and versatility

• Glow plug and spark plug service in engine bays
• Valve cover bolts, timing components, and related fasteners
• Diesel systems and turbo installations where space is tight
• Clutch bleeders and other common automotive tasks
• General maintenance and repair in both automotive and industrial settings

While this set focuses on metric sizes, you can pair it with other tools for a complete solution that prepares you for a wide range of tasks. The compact 3/8-inch drive size blends well with many ratchets and adapters, giving you flexible options for both high torque and delicate tightening. Consider how the extra reach might reduce the time you spend contending with crowded spaces, especially during routine maintenance or repair work. This is not a guarantee of faster results, but it offers a practical approach to tackling common bottlenecks in mechanical projects.
