Der Erwachte O2 Sensor Socket Set 6PCS — 22mm (7/8") Sockets with M12 & M18 Thread Chasers, CR-V Durability

Der Erwachte 6PCS O2 Sensor Socket Set is a complete, professional-grade toolkit for removing, installing and restoring oxygen and thermal sensor threads on most cars, trucks and SUVs.

If you work on exhaust systems or perform routine engine maintenance, getting oxygen sensors out intact and restoring damaged threads are common challenges. This 6-piece set combines the most frequently used O2 sensor sockets, a thermal sensor switch socket and two precision thread chasers so you can remove seized sensors, install replacements and repair stripped threads without improvising with the wrong tools.

How does this set make oxygen sensor removal easier?

The sockets are sized to the most common O2 sensor fittings (7/8" / 22mm) and include both 1/2" and 3/8" drive offset options to reach sensors tucked into narrow engine bays. Offsets let you work around wiring and brackets while applying steady torque, reducing the risk of crushing sensor housings or fraying wires.

• Includes 7/8" (22mm) sockets with 1/2" and 3/8" drives for versatility.
• Offset shapes provide clearance in tight engine compartments.
• Knurled surfaces improve grip when hands are oily or greasy.
• Thermal sensor switch socket covers additional sensor types.

Will the tools hold up under repeated shop use?

Yes — every piece is forged from chrome vanadium steel for high hardness and corrosion resistance, so they tolerate frequent use and exposure to harsh under-hood conditions. The finish and machining reduce wear on fasteners and maintain fit over time.

• Chrome vanadium (CR-V) construction for durability and rust resistance.
• Precision-machined sockets to minimize rounding of sensor hexes.
• Heat-treated components to withstand higher torque demands.
• Lightweight yet rugged design for shop or mobile use.

How do the thread chasers restore damaged sensor threads?

The included M12 x 1.25mm and M18 x 1.5mm thread chasers are made to clean and re-cut stripped or contaminated threads in oxygen sensors and exhaust manifolds. They remove corrosion and carbon deposits that prevent proper seating of replacement sensors, allowing new parts to torque to specification.

• M12 x 1.25mm and M18 x 1.5mm sizes cover common O2 sensor and manifold threads.
• Precision threads realign damaged grooves without overcutting.
• Use before installation to ensure correct sensor torque and sealing.
• Helps avoid costly manifold repairs or thread inserts in many cases.

What other practical features help during repairs?

Every socket has a knurled grip to help hand-turn stubborn sensors and a profile that protects sensor bodies and wiring. The set was organized to be portable and convenient for professional technicians and DIYers who need a reliable, all-in-one solution for sensor service jobs.

• Knurled sockets enhance manual control for initial loosening.
• Compact kit footprint fits most toolboxes or mobile carts.
• Compatible with most domestic and imported vehicles.
• Includes thermal sensor switch socket for broader coverage.

Who is this for? If you are a professional mechanic, a mobile technician or a hands-on car owner who performs exhaust and engine diagnostics, this Der Erwachte 6PCS O2 Sensor Socket Set brings the correct sizes and thread repair tools in one kit. It’s especially useful for shops that frequently replace oxygen sensors, for restorations where threads are corroded, and for anyone who wants to avoid damaging sensors and wiring during removal. The set is compact enough to carry on service calls and robust enough to stand up to repeated shop use.
