A ABIGAIL O2 Oxygen Sensor Socket Kit 5-Piece — Offset Sockets & Thread Chasers, Chrome-Moly

The A ABIGAIL 5-piece kit is a compact, offset oxygen sensor socket and thread chaser set designed to remove, install, and repair O2 sensors and related fittings even in tight engine spaces.

This toolkit groups specialized sockets and thread chasers engineered to handle oxygen (O2) sensors, hex vacuum switches, and damaged sensor threads. Built from chrome-moly steel with a black oxide finish, the set balances reach, clearance, and corrosion resistance so you can work with wiring harnesses attached and gain extra leverage where a straight socket won’t fit.

How does this set make O2 sensor removal easier?

The sockets feature a slotted, low-profile six-point design that accepts the sensor wiring harness while gripping the sensor hex. Offset and deep broach options give you different angles and depth to clear obstructions. Use with a ratchet or breaker bar for controlled torque without cutting the harness.

• Slotted 6-point design accommodates sensor wiring harnesses.
• Offset crowfoot provides reach in crowded engine bays.
• Extra-deep broach socket fits recessed sensor bodies.
• Works with standard 3/8" drive ratchets and breaker bars.

What tools are included and when should I use each piece?

The kit contains five pieces sized and shaped for specific tasks: an extra-deep broach socket, low-profile crowfoot, offset crowfoot, and two thread chasers for common O2 sensor threads. Each item addresses a different clearance or thread-restoration need so you can pick the right tool for the situation.

• 1× 3/8" drive extra-deep broach socket (47mm long) for recessed sensors.
• 1× 3/8" drive low-profile crowfoot (29mm) for tight vertical clearances.
• 1× 3/8" drive offset crowfoot (78mm) for awkward angles and leverage.
• 1× M18 x 1.5mm and 1× M12 x 1.25mm thread chasers to clean/repair sensor threads.

Are these tools durable and safe for repeated garage use?

The pieces are forged from chrome-molybdenum and solid cast steel, then treated with a black oxide finish to resist rust. That construction provides the strength required for stubborn sensors while helping prevent rounding and stripping when used correctly with compatible ratchets.

• Chrome-moly construction for higher tensile strength.
• Black oxide finish reduces corrosion after repeated use.
• Six-point engagement minimizes slippage on hex flats.
• Designed for 3/8" drive tools to match common garage equipment.

What should I know about using the thread chasers?

The included M18 and M12 thread chasers restore damaged or corroded sensor threads so a new sensor seats properly. Run them carefully by hand or with a 3/8" drive at low torque to avoid cutting new threads; they are intended to clean and realign, not rethread a badly stripped housing.

• Use chasers to remove corrosion and debris from sensor holes.
• Operate slowly and with light pressure to protect housing threads.
• Fit onto 3/8" drive tools for controlled turning.
• Check fit with a new sensor before final installation.

Who is this for? This A ABIGAIL 5-piece set is aimed at DIY mechanics, professional technicians, and garage owners who need a compact, versatile solution for O2 sensor service and thread repair. If you frequently work in cramped engine compartments or restore vehicles with corroded sensor ports, this kit gives targeted sockets and chasers that reduce removal time and lower the risk of damaging wires or hex flats.
