WORKPRO Oxygen Sensor Socket Set 7PCS — 3/8" & 1/2" Drive, Offset Wire-Gate for Sensor Removal

WORKPRO 7PCS O2 Oxygen Sensor Socket is a compact professional toolkit for removing, installing, and servicing oxygen, thermal and pressure sensors using 3/8" and 1/2" drives while protecting sensor wiring.

This seven-piece set combines offset sockets, a wire-gate design, specialty sensor sockets and two thread chasers to streamline common automotive sensor jobs. Built from alloy steel with phosphating and heat treatment, the set is made to resist wear while delivering accurate fit and strong torque transfer. The included thread chasers restore M12 and M18 threads so you can avoid cross-threading and get sensors seated correctly after service.

How does this set make oxygen sensor removal easier?

The WORKPRO sockets include offset and open-back designs with a wide wire gate so the sensor’s cable can pass through without pinching. The offset sizes let you clear obstruction from heat shields or exhaust flanges, while the slotted square drive improves engagement with your ratchet to reduce slipping.

• 7/8" (22mm) offset sockets for O2 sensors, in both 3/8" and 1/2" drive sizes
• Wire-gate socket keeps sensor wiring safe during turn-out
• Slotted square hole for better anti-slip ratchet connection
• Offset geometry clears tight exhaust and manifold areas

Which tools are included and what do they do?

The kit contains seven purpose-built pieces: two offset oxygen-sensor sockets, a wire-gate sensor socket, two larger sensor sockets for thermal or oil pressure sensors, and two threaded chasers for M12 and M18. Together they cover most car and light-truck sensor sizes, and the chasers let you clean damaged threads before installing a new sensor.

• 1/2" drive x 7/8" (22mm) offset oxygen sensor socket
• 3/8" drive x 7/8" (22mm) offset oxygen sensor socket
• 3/8" drive x 7/8" (22mm) wire-gate oxygen sensor socket
• 3/8" drive x 1-1/16" (27mm) thermal sensor switch socket
• 3/8" drive x 1-1/16" (27mm) oil pressure sensor socket
• M12 x 1.25mm and M18 x 1.5mm thread chasers for repair and prevention

What materials and finishes ensure durability?

WORKPRO manufactures these sockets from high-grade alloy steel and subjects them to heat treatment to strengthen critical areas. A phosphated surface finish improves corrosion resistance and reduces galling, so sockets maintain fit and function after repeated use.

• Alloy steel construction for high torque tolerance
• Heat-treated components for longer service life
• Phosphate finish to resist rust and wear
• Precision-machined openings for secure sensor fit

How do the thread chasers add value during sensor service?

The included M12 and M18 thread chasers repair and straighten damaged threads so replacement sensors seat correctly and torque accurately. Using a chaser reduces the risk of cross-threading and the need for more invasive repairs like helicoils or replacement housings.

• M12 x 1.25mm for common O2 sensor ports
• M18 x 1.5mm for larger pressure or temperature sensors
• Fits 3/8" ratchet for controlled cleaning action
• Restores threads quickly to accept new sensors securely

Who is this for: The WORKPRO 7PCS O2 Oxygen Sensor Socket set is aimed at home mechanics, professional technicians, and DIY enthusiasts who work on exhaust, engine, and sensor maintenance. If you need a compact toolkit that handles common O2, thermal and oil pressure sensor sizes, protects sensor wiring during removal, and repairs thread damage, this set is designed to speed up repairs and reduce the chance of installation errors.
