HTOMT Oxygen Sensor Socket Set 5PCS — Deep & Low-Profile Sockets with Thread Chasers, Cr-V

HTOMT 5PCS Oxygen Sensor Socket Set is a compact, workshop-ready kit for removing, installing and restoring threads on O2 sensors and vacuum switches.

This five-piece set combines deep and low-profile oxygen sensor sockets, offset crowfoot access, plus two thread chasers in a molded carry case. Built from chromium-vanadium steel with protective plating, the kit is made to resist corrosion and reach sensors in tight engine bays while protecting wiring. It’s designed for mechanics, home DIYers and fleet technicians who need reliable access to heated and unheated oxygen sensors without damaging connectors or threads.

How does this set reach sensors in cramped engine bays?

The kit includes both extra-deep and low-profile sockets and an offset crowfoot so you can adapt to different clearances. A side-cut design lets the socket straddle wiring and harnesses so you can work around sensor cables without stressing them.

• 3/8" drive extra-deep broach socket (3-1/8") for recessed sensors
• 3/8" low-profile crowfoot (1-1/4") for shallow access points
• 1/2" offset crowfoot (1-15/16") for angled approaches
• Side-cut openings to preserve sensor wiring during removal

What sizes and tools are included to fit most vehicles?

The set covers the common hex sizes and drive interfaces used on modern oxygen sensors. Two thread chasers for M18 x 1.5 and M12 x 1.25 restore damaged threads so new sensors seat correctly.

• 6-point 7/8" (22 mm) socket opening for hex-style O2 sensors
• 3/8" and 1/2" drive ends fit standard ratchets and breaker bars
• M18 x 1.5 and M12 x 1.25 thread chasers with 3/8" drive
• Packaged in a high-impact ABS case for organized storage

How durable are these wrenches and thread chasers?

Forged from chromium-vanadium steel and finished with phosphating and electroplating, these pieces resist rust and wear through repeated shop use. The material choice and protective coating extend service life while keeping edges and drive surfaces strong under torque.

• High-strength Cr-V steel construction for longevity
• Phosphate and electroplate finish to reduce corrosion
• Precision-machined 6-point opening for grip and torque transfer
• Heat-treated components maintain shape under load

What makes this set easier to carry and organize?

Each tool nests into a molded red ABS carry case that keeps sockets and chasers secure and visible. The compact case fits most toolboxes and is handy for mobile technicians who need to transport the kit between jobs.

• High-impact ABS molded case prevents tool migration
• Individual slots prevent metal-to-metal contact and wear
• Compact footprint fits in standard tool drawers or vans
• Clear layout means you can inventory the kit at a glance

Who is this for: The HTOMT 5PCS Oxygen Sensor Socket Set suits professional mechanics, DIY car owners and fleet service technicians who encounter a range of oxygen sensor locations and occasional thread damage. If you need reliable, corrosion-resistant sockets that protect sensor wiring and include thread repair tools, this kit provides the versatile access and thread restoration features common in everyday automotive maintenance.
