HTOMT Oxygen Sensor Socket Set 5PC — Red Case, O2 Saver Sockets & Thread Chasers (M12/M18)

The HTOMT 5PCS Oxygen Sensor Socket Set is a compact kit of deep, low-profile and offset sockets plus thread chasers designed to safely remove, install and repair O2 sensors and vacuum switches on most vehicles.

Keep sensor work fast and damage-free with a purpose-built toolkit. These five tools are forged from chromium vanadium steel, finished to resist corrosion, and arranged in a durable red ABS case for easy transport. The set combines three saver-style sockets for tight or wire-bound sensor locations and two thread chasers to restore or clean M12 and M18 threads before reinstalling sensors.

How does this set make oxygen sensor removal easier?

The sockets include side cutouts so you can slide the tool over sensor wires without crimping or severing them. You get a deep broach socket for recessed sensors, and low-profile and offset crowfoot styles to reach sensors blocked by manifolds or heat shields. Using the right shape socket reduces the time spent struggling with awkward angles.

• 3/8" drive extra-deep broach socket (3-1/8" long) for recessed sensors
• 3/8" low-profile crowfoot (1-1/4" long) for shallow clearances
• 1/2" offset crowfoot (1-15/16" long) for obstructed access
• Side cut design protects sensor wiring during removal

Will the thread chasers really help reinstallation?

Yes — the kit includes M18 x 1.5mm and M12 x 1.25mm thread chasers that clean rust, carbon and cross-thread damage to improve fit and torque accuracy. Using a chaser before installing a sensor reduces the risk of misthreading and helps the sensor seat correctly for a reliable seal. They accept a 3/8" drive so you can use a ratchet or breaker bar for controlled threading.

• M18 x 1.5mm and M12 x 1.25mm sizes match common O2 sensor threads
• 3/8" drive compatibility for easy ratchet use
• Restores damaged threads to prevent cross-threading
• Speeds accurate installation and improves sealing

What materials and finishes protect the tools during shop use?

HTOMT forges the sockets and wrenches from high-strength chromium vanadium steel for durability under torque. The exterior receives phosphating and electroplating to resist oxidation and corrosive garage conditions. Together these treatments extend service life and keep mating surfaces smooth for reliable engagement with sensor hexes and drives.

• Chromium vanadium steel construction for strength and toughness
• Phosphated and electroplated finish to resist rust
• 6-point 7/8" (22mm) socket opening fits standard hex O2 sensors
• Designed for repeated shop use and storage in the included case

How portable and organized is the set for mobile or home mechanics?

All five pieces snap into a high-impact red ABS carry case that keeps components organized and protected. The compact case fits into a toolbox, under a seat, or in a service van without adding bulk. Quick visual access to each tool decreases search time and keeps threads and sockets clean between jobs.

• Compact red ABS storage case for neat transport and protection
• Each tool has a designated slot to prevent loss or damage
• Case dimensions suit shop drawers and mobile tool rigs
• Lightweight design for easy carrying to roadside or bay

Who is this for? The HTOMT 5PCS Oxygen Sensor Socket Set is tailored for DIYers, home mechanics and professional technicians who regularly service emissions systems, replace O2 sensors or need reliable access tools for hard-to-reach sensor locations. If you work on vehicles with heated or non-heated oxygen sensors, inspect vacuum switches, or want to avoid splicing sensor wires, this compact kit provides the most-used sizes and thread chasers to get the job done cleanly and quickly.
