Description
O2 Sensor Socket Set, 5 Piece Oxygen Sensor Socket Set with Thread Chaser
-
The wiring harness is no obstacle: the wide wire gate lets this O2 sensor tool pass over the sensor wiring harness without damage
-
Awkward sensors become reachable: offset construction and a side cutout design give easier access from different angles while protecting wires
-
A grip that holds: the slotted anti-slip design helps the sockets grip and gives better leverage and control
-
Tools that keep their shape: forged chrome vanadium steel offers excellent durability and torque resistance to help prevent deformation or breakage
-
The right size is in the set: the 6-point 7/8 inch opening fits most hex oxygen sensors on 3/8 inch and 1/2 inch drive ends
Pulling an oxygen sensor is a job where the wiring harness, the tight spot and a slipping tool all get in your way. This set is built for exactly that: a wide wire gate passes over the harness without damage, and the offset construction gives you easier access to hard-to-reach areas with better leverage and control. The 7/8 inch offset sockets use common drive ends, so your ratchet or breaker bar fits.

Forged from premium chrome vanadium steel with a heat-treated, phosphated surface, these mechanic tools resist deformation and breakage. The 0.9 in (22mm) O2 sensor socket styles cover offset and long sensor locations, and with the two thread chasers the set works as an O2 sensor removal tool for oxygen sensors and vacuum switches on computer-controlled engines.

Key Features
Among car repair tools and automotive tools, this set stands out for these features:
-
Comprehensive set: The kit holds a 1/2” Dr. x 7/8” (22mm) offset socket, a 3/8” Dr. x 7/8” (22mm) offset socket, a 3/8” Dr. x 7/8” (22mm) long socket, an M12 x 0 in (1.25mm) thread chaser and an M18 x 0.1 in (1.5mm) thread chaser, one piece of each, for automotive oxygen sensor removal and installation.
-
Durable and reliable: Premium forged chrome vanadium steel gives the tools excellent durability and torque resistance, helping prevent deformation or breakage and supporting long-lasting performance.
-
Innovative design: The gate, the slots and the offset shape work together so the tool travels safely over the wiring and keeps better control in tight areas.
-
Wide application: Use it to remove and install oxygen sensors and vacuum switches on computer-controlled engines, with three socket styles covering different sensor locations and repair needs.
-
Practical fit: The universal 6-point 7/8” (22mm) socket opening fits most hex oxygen sensors, and the common 3/8” and 1/2” drive ends can be used with ratchets or breaker bars.
-
Wide wire gate: The gate is wide enough for the socket to travel over the harness that carries the sensor wiring, and nothing gets damaged.
-
Slotted anti-slip design: Slots on the sockets improve grip and add leverage and control during use.
-
Offset construction: The offset shape reaches hard-to-reach areas more easily.
-
Side cutout design: A side cutout makes it possible to reach sensors from varied angles and shields the wires.
-
Heat-treated phosphated surface: Heat treatment and a phosphated finish add strength and corrosion resistance.

Right for you if
-
✓The sensor harness blocks a normal socket — a wide wire gate passes over the wiring harness
-
✓Your sensor sits in a tight spot — offset construction and a side cutout reach it from different angles
-
✓You turn with a ratchet or breaker bar — 3/8” and 1/2” drive ends
-
✓You work on computer-controlled engines — removes oxygen sensors and vacuum switches
If two or more of these sound like you, this is the one.
