WORKPRO O2 Oxygen Sensor Socket Set 7-Piece — 3/8" & 1/2" Drive, Wire-Slot + Thread Chasers

This seven-piece set combines dedicated sensor sockets and two thread chasers to speed up common automotive sensor jobs. Each socket features a wide wire slot that protects sensor wires while the slotted square hole prevents ratchet slippage. Made from heat-treated alloy steel with a phosphated finish, the set balances corrosion resistance with toughness for repeatable use in garages and home workshops.

How does this set make oxygen sensor removal easier?

The sockets are shaped to accept sensor bodies while leaving room for wiring, so you don’t need to cut or disconnect fragile leads. Offset and straight socket designs let you reach sensors in tight exhaust or engine locations without stretching or awkward leverage.

• Includes 7/8" (22 mm) and 1-1/16" (27 mm) sensor-fit sockets for common sensor sizes
• Wide wire gate keeps wiring intact during removal and installation
• Offset 1/2" drive socket provides clearance around exhaust pipes
• Slotted square hole reduces ratchet slip for safer torque application

What thread issues do the included chasers resolve?

The M12 x 1.25 and M18 x 1.5 thread chasers clean and restore damaged sensor threads in cylinder heads or exhaust components. Using the correct chaser prevents cross-threading and speeds reinstallation of replacement sensors.

• M12 x 1.25 chaser for smaller sensor ports and threaded fittings
• M18 x 1.5 chaser for larger oxygen/pressure sensor openings
• Fits a 3/8" ratchet for controlled, manual thread restoration
• Helps ensure accurate seating and leak-free sensor fitment

Which features improve durability and grip under shop conditions?

WORKPRO manufactured these tools from high-grade alloy steel and applied heat treatment for improved strength under torque. A phosphated surface finish reduces rust and provides a nonslip texture for handling with oily hands.

• Heat-treated alloy steel construction for long-lasting service
• Phosphate finish resists corrosion in garage environments
• Slotted square hole design prevents ratchet rounding and slipping
• Precision-machined sockets for consistent sensor fit

Which vehicles and sensor types will this set cover?

The assortment covers the most commonly encountered oxygen, thermal, oil pressure, and vacuum sensor sizes used across many passenger vehicles. While it won’t fit every specialty or metric size, it handles the majority of routine repair and maintenance tasks.

• Designed for O2 sensors, thermal sensors, oil pressure and vacuum sensors
• Includes 7/8" (22 mm) and 1-1/16" (27 mm) sockets for common sensor diameters
• Applicable to many domestic and import cars and light trucks
• Thread chasers support correct reinstallation after cleaning or repair

Who is this for: The WORKPRO 7PCS O2 Oxygen Sensor Socket Set is aimed at DIY mechanics, professional technicians, and anyone maintaining a home garage who needs a reliable, compact kit for sensor service. It’s especially useful when sensors are hard to reach or when thread damage must be corrected before fitting new parts.
