ITEQ Oxygen Sensor Socket Set 5-Pc — 7/8" (22mm) Sockets with M18 & M12 Thread Chasers, 3/8" & 1/2" Drive

ITEQ 5-piece oxygen sensor socket and thread chaser set is a compact mechanic’s kit designed to remove, install, inspect and repair heated and non-heated oxygen sensors safely without damaging wiring or threads.

This professional-grade collection brings together three specialized sockets and two thread chasers to handle most sensor access scenarios on modern computer-controlled engines. Each socket features a 6-point 7/8" (22mm) opening and a side cutout to clear sensor wires while allowing use with standard 3/8" or 1/2" drive tools. The included M18 x 1.5mm and M12 x 1.25mm thread chasers restore damaged sensor threads, saving time and reducing the need for expensive repairs.

How does this set make oxygen sensor removal easier?

The sockets are engineered to reach awkwardly located sensors and protect the wiring harness during removal. The side-cutout design permits turning the socket without pinching or cutting sensor wires, and the 6-point profile grips hexagon sensor bodies firmly to avoid rounding.

• Three socket styles (extra-deep, low-profile crowfoot, offset crowfoot) to access different depths and angles.
• Side cutouts prevent wire damage and allow access in tight engine bays.
• Fits standard 3/8" and 1/2" ratchets or breaker bars for torque versatility.

What specific components are included and why they matter?

The kit contains tools selected to cover common on-vehicle situations: an extra-deep broach socket for recessed sensors, a low-profile crowfoot for constrained vertical space, and an offset crowfoot for sensors behind brackets. Two thread chasers clean and repair metric threads frequently used on oxygen sensors to ensure reliable reseating.

• 1 × 3/8" drive extra-deep broach socket (3-1/8" long) — reaches deeply recessed sensors.
• 1 × 3/8" drive low-profile crowfoot (1-1/4" long) — fits tight vertical clearances.
• 1 × 1/2" drive offset crowfoot (1-15/16" long) — works around obstructions and brackets.
• 1 × M18 x 1.5mm and 1 × M12 x 1.25mm thread chasers — restore sensor threads for secure installation.

Will these sockets fit my vehicle and tools?

The sockets use a universal 7/8" (22mm) hex opening that matches nearly all oxygen sensors and accept both 3/8" and 1/2" drive connections common on hand ratchets and breaker bars. The metric thread chasers cover the two most common sensor thread pitches, making the kit applicable to a broad range of makes and models.

• 6-point 7/8" (22mm) opening fits standard oxygen sensor hex bodies.
• Compatibility with 3/8" and 1/2" drive tools for flexible use with existing toolsets.
• Thread chasers sized for M18 x 1.5mm and M12 x 1.25mm sensor threads on many vehicles.

How does the set prevent additional repairs or sensor damage?

The side slot design and 6-point socket grip reduce the chance of wiring abrasion and hex rounding during removal or installation. When threads are damaged, the included chasers clean and re-form the thread pattern so sensors seat properly, cutting down on cross-threading and leakage risks.

• Side cutouts offer safe clearance for sensor wiring and connectors.
• 6-point socket profile minimizes slippage and rounded flats.
• Thread chasers mend damaged threads to enable correct, secure sensor reinstallation.

Who is this for? This ITEQ set is aimed at professional mechanics, DIY enthusiasts and automotive technicians who work on modern fuel-management systems and need a compact, versatile solution for oxygen sensor service. It’s especially useful if you regularly encounter recessed or hard-to-reach sensors, or if you want to avoid replacing damaged sensor ports by repairing threads on the spot.
