WORKPRO O2 Oxygen Sensor Socket Set, 6pc (3/8" & 1/2" Drive) with M12/M18 Thread Chasers, Alloy Steel

WORKPRO 6PCS O2 Oxygen Sensor Socket set is a purpose-built kit for removing, installing, and servicing oxygen, thermal and oil pressure sensors on most vehicles, including two thread chasers for repairing damaged sensor threads.

This compact PROFESSIONAL-GRADE set gives mechanics and DIYers the right sockets and tools to reach awkward sensors, protect sensor wiring, and restore damaged threads without replacing the cylinder head. The kit combines offset and straight socket designs in both 3/8" and 1/2" drives plus two M12 and M18 thread chasers to clear and realign sensor threads. Constructed from alloy steel with phosphating and heat treatment, the components resist rust and withstand repeated use in garage conditions.

Which sensor types can I service with this WORKPRO kit?

The set covers oxygen (O2) sensors, thermal switches, oil pressure and vacuum sensors. Sockets are sized to fit common sensor hex dimensions and work with both 3/8" and 1/2" drive ratchets or extensions for added reach.

• 1/2" drive 7/8" (22mm) offset O2 socket for larger ratchets
• 3/8" drive 7/8" (22mm) offset and straight O2 sockets
• 3/8" drive 1-1/16" (27mm) thermal sensor switch socket
• M12 x 1.25 and M18 x 1.5 thread chasers for damaged threads

How does the design protect sensor wiring and prevent slipping?

Each socket includes a wide wire gate that lets sensor wiring pass through without kinking or cutting the cable, keeping electrical leads intact during removal. The slotted square hole on the sockets improves grip and reduces the chance of ratchet slippage when torqueing stubborn fittings.

• Wide wire gate keeps sensor harnesses safe when pulling or loosening
• Slotted square hole provides better anti-slip contact with drive tools
• Offset options help access sensors in tight engine bays

Are the sockets durable enough for repeated shop use?

Yes — the WORKPRO kit is forged from alloy steel and receives heat treatment plus phosphating to harden the metal and resist corrosion. That combination improves fatigue resistance, so the tools remain reliable across many service cycles.

• Alloy steel construction for strength under torque
• Heat treatment increases durability and wear resistance
• Phosphate finish helps guard against rust in humid garages

What practical advantages do the included thread chasers offer?

The M12 and M18 thread chasers let you clean, realign, or restore sensor threads in the cylinder head or housing, preventing cross-threading when installing new sensors. They save time and expense by avoiding thread repairs or part replacements when threads are only slightly damaged.

• M12-1.25 and M18-1.5 sizes match common sensor thread pitches
• Straightening threads reduces installation resistance and leaks
• Compact chasers are easy to carry in a tool roll or box

Who is this for? The WORKPRO 6PCS O2 Oxygen Sensor Socket set suits professional technicians, home mechanics, and automotive enthusiasts who need a reliable, compact toolkit to service oxygen and thermal sensors without damaging wires or threads. It’s especially useful for vehicles with hard-to-reach sensors or where thread condition is suspect — a practical kit that reduces downtime and helps get accurate sensor installs on many makes and models.
