Der Erwachte O2 Sensor Socket Set 6PC — 22mm & 27mm Sockets with M12/M18 Thread Chasers, Chrome Vanadium

Der Erwachte 6PCS O2 sensor socket set is a complete professional-grade kit for removing, installing and repairing oxygen/thermal sensor threads on most cars, trucks and SUVs.

This compact toolkit gathers the common 22 mm (7/8") oxygen sensor sockets, a 27 mm thermal sensor switch socket, and two metric thread chasers into one durable set. Built from chrome vanadium steel and designed with offsets and knurled grips, it helps mechanics and DIYers access sensors in cramped engine bays while protecting wiring and exhaust components. The set is optimized to cover domestic and imported vehicles and to restore damaged sensor threads so new sensors seat correctly.

How will this kit speed up oxygen sensor removal?

The set includes both 1/2" and 3/8" drive 7/8" sockets and an offset shape to clear harnesses and heat shields. That makes it faster to reach and remove stuck sensors without bending wires or removing adjacent parts.

• Two offset 7/8" (22 mm) sockets for tight spaces and different ratchet drives
• Knurled surfaces for secure hand turning before using a ratchet
• Chrome vanadium construction for strength during stubborn removals
• Thermal switch socket for larger sensors and switches

Can this kit repair damaged sensor threads?

Yes — the included M12 x 1.25 mm and M18 x 1.5 mm thread chasers clean and re-cut damaged threads in exhaust manifolds and sensor housings. Using the correct chaser restores the thread profile so replacement sensors fit and seal properly.

• Two metric thread chasers covering common sensor thread sizes
• Precision-machined teeth to remove corrosion and burrs without over-cutting
• Use before sensor installation to prevent cross-threading or leaks
• Compact size keeps chasers handy in any toolbox

What makes these sockets durable and shop-ready?

The sockets are forged from chrome vanadium steel and heat-treated for hardness and wear resistance. Corrosion-resistant finish and precise machining deliver long service life even under repeated shop use.

• CR-V alloy for strength and resistance to rounding under torque
• Offset geometry retains socket strength while improving access
• Polished surfaces that resist rust and simplify cleaning
• Professional-grade tolerances suited for OEM-style sensors

How do I use the set safely without damaging sensors or wiring?

Start by disconnecting the sensor wiring harness, then use the offset socket to clear any shielding. Apply steady, controlled torque with the proper drive size and use the thread chaser only when threads are visibly damaged or corroded.

• Disconnect electrical connector before loosening sensor
• Choose 1/2" or 3/8" drive to match your ratchet or breaker bar
• Use thread chaser gently to avoid removing material unnecessarily
• Confirm sensor seating and torque to vehicle manufacturer specs

Who is this for? Mechanics, fleet maintenance teams and serious DIYers who need a compact, reliable set for oxygen and thermal sensor work will benefit most. The kit’s combination of common 22 mm sockets, a larger thermal-sensor socket and two thread chasers covers most sensor removal, installation and thread-repair scenarios encountered on modern cars, trucks and SUVs. If you frequently replace sensors or service exhaust components, this lightweight, durable Der Erwachte set streamlines the job and reduces the risk of damaging threads or wiring.
