DAYUAN 22mm 1/2" Drive Lambda Oxygen Sensor Offset Removal Socket Tool + Hole Wire 26-8

Make sure you have sufficient leverage to unscrew but take care not to shear the head off! These nuts get really quite well stuck with emissions.

Worked fine. Quite weighty and appears to be made from cobalt steel. Used on a Bosch O2 sensor.

Would recommend

Had to revert to a standard 22 mm OE spanner. As as soon as any leverage is applied, this socket speads and slips. Looks the part, but is not fit for purpose

Used to remove lambda sensor, important to use penetrative oil before use and take it gently to avoid the socket opening up and slipping 👍🏻

Arrived quickly & did exactly what I needed, made the job really easy

Not very strong

Cheap price, but that's it . Not made very precise as doesn't fit the size it says.
