Der Erwachte O2 Sensor Socket Set 6PCS – Offset 7/8in (22mm), Thread Chasers, 1/2 & 3/8 Drive

This compact toolkit brings six purpose-built tools to routine exhaust-sensor jobs: multiple drive-size sockets sized for common O2 sensors, a thermal-sensor switch socket, and two precision thread chasers to repair damaged sensor threads. Designed for garages and DIYers alike, the set focuses on access, longevity and thread restoration so you can finish sensor replacements cleanly without stripping or cross-threading fasteners.

How does this set make tight engine-bay work easier?

The sockets include offset geometry and both 1/2" and 3/8" drive interfaces so you can reach sensors that sit behind brackets, heat shields, or wiring harnesses. Offset sockets let you apply torque while avoiding contact with fragile sensor leads or nearby exhaust components.

• Offset 7/8" (22mm) sockets for common O2 sensor hexes
• 1/2" and 3/8" drive options for ratchets and breaker bars
• Reduced risk of damaging sensor wiring thanks to recessed socket openings
• Slim profiles help enter confined spaces where straight sockets cannot

What sizes and tools are included and why they matter?

The kit bundles the most frequently needed sizes for oxygen sensors plus a thermal sensor switch tool and two thread restoration tools. That combination covers removal, installation and thread repair so you won’t need separate purchases for most exhaust-sensor tasks.

• 7/8" (22mm) sockets in offset and straight configurations — fits the majority of O2 sensors
• 1-1/16" (27mm) thermal sensor switch socket for temperature/thermal senders
• M12 x 1.25mm and M18 x 1.5mm thread chasers to restore damaged sensor threads
• Both 3/8" and 1/2" drive options included for tool compatibility

How durable and reliable is the construction?

All sockets and chasers are manufactured from chrome vanadium (CR-V) steel and heat-treated for toughness. Precision machining and surface finishing resist corrosion and wear so the tools retain their fit and function under repeated shop use.

• Heat-treated CR-V for improved strength and long service life
• Corrosion-resistant finish to prevent premature rusting
• Knurled gripping surfaces on sockets for secure handling with oily hands
• Thread chasers cut cleanly to realign and restore worn or damaged threads

Can this kit be used across different vehicles?

The combination of common O2 sensor sizes, thermal switch socket and two popular thread pitches means broad vehicle compatibility. It serves most domestic and import cars, SUVs and light trucks that use 22mm oxygen sensor hexes and M12/M18 thread standards.

• Fits many OEM and aftermarket oxygen sensors with 22mm hexes
• Thread chasers match common sensor thread pitches for repairs
• Works with a wide range of passenger vehicles and light-duty trucks
• Useful for both professional shops and at-home repairs

Who is this for: The Der Erwachte 6PCS O2 Sensor Socket Set suits automotive technicians, mobile mechanics and motivated DIY owners who want a single, portable kit for sensor swaps and thread recovery. If you routinely work on exhaust systems or need a dependable set for occasional O2 sensor replacement, this kit provides the right sizes, durable materials and repair tools to get the job done with less risk of damaging threads or sensor leads.
