Finally! A socket that doesn't 'bloom' under pressure. I used a 2-foot breaker bar on my rusted-out heavy-duty truck and this thing didn't even flinch. If you live in a region with high corrosion, you need this.

Saved me so much frustration. The slot is wide enough for the wire but the walls are thick enough to get a real grip. Changed the O2 sensor on my sedan in 15 minutes flat.

This heavy-duty oxygen sensor socket is built to handle the most stubborn, seized sensors. Its reinforced walls ensure it won't spread or slip, making even the toughest exhaust repairs simple and efficient for any home mechanic.
