A ABIGAIL 5-Piece Oxygen Sensor Socket Set — Offset Sockets & Thread Chasers, Black-Oxide

The A ABIGAIL 5 PCS Oxygen Sensor Socket Set is a compact, offset tool kit designed to remove and install O2 sensors and clean damaged sensor threads even in tight engine bays.

This five-piece kit groups specially shaped sockets and two thread chasers to tackle stubborn oxygen sensors and hex vacuum switches without disconnecting sensor wiring. Each tool is crafted from chrome-moly steel with a black-oxide finish to resist corrosion while withstanding the leverage needed to free seized sensors. The set combines depth, low-profile, and offset options so you can reach awkward angles with a ratchet or breaker bar and restore sensor threads for reliable reassembly.

How does this set make oxygen sensor removal easier?

The kit includes dedicated sockets with slots and offsets so you can work around attached wiring harnesses and limited clearance. The 6-point low-profile design grips sensor hexes securely to reduce slipping and rounding while the extra-deep broach accommodates longer sensor bodies.

• 3/8" drive extra-deep broach socket (47 mm long) for deep-mounted sensors
• 3/8" drive low-profile crowfoot socket (29 mm long) for tight vertical spaces
• 3/8" drive offset crowfoot (78 mm long) for hard-to-reach angles
• Slotted sockets allow the wiring harness to remain attached during removal

What thread chasers are included and when should I use them?

The set contains two thread chasers in common oxygen-sensor pitches to repair damaged or corroded sensor threads before reinstalling a sensor. Use the appropriate chaser to clean cross-threading, corrosion, or debris so the new or serviced sensor seats correctly and torques to spec.

• M18 x 1.5 mm chaser for many European and Asian O2 sensors
• M12 x 1.25 mm chaser for smaller sensor ports
• 3/8" drive compatibility lets you use your ratchet or breaker bar

Are these tools durable and compatible with standard ratchets?

Yes—the sockets and chasers are forged from chrome-molybdenum and cast steel, then finished with black oxide to resist rust and extend service life. Each piece accepts a 3/8" drive so they pair with common ratchets, breaker bars, and extensions used in garages and home workshops.

• High-strength chrome-moly construction minimizes deformation under torque
• Black-oxide finish reduces corrosion and surface wear
• 3/8" drive fits standard ratchets and torque tools

What sizes and lengths are included to reach different sensor locations?

The kit balances compact and longer tools so you can adapt to both shallow and recessed sensor positions. From an extra-deep broach to a long offset crowfoot, these lengths are chosen to access ports that are blocked by manifolds, heat shields, or wiring.

• Extra-deep broach: 47 mm (1.85 in) for recessed sensors
• Low-profile crowfoot: 29 mm (1.15 in) for constrained clearance
• Offset crowfoot: 78 mm (3.1 in) to reach around obstructions

Who is this for: This A ABIGAIL 5-piece set is aimed at DIY mechanics, professional technicians, and automotive enthusiasts who frequently service exhaust or emission components. It’s ideal if you need to remove stuck O2 sensors without cutting wires, restore damaged sensor threads, or simply expand your toolbox with specialized, workshop-grade sockets that fit standard 3/8" drive tools. If you want fewer trips to the shop and cleaner sensor installations at home, this kit provides the essential shapes and thread tools to get the job done.
