1/2" Crowsfoot Wrenches Flare Nut Style (Metric)

It worked for 02 sensor

Be sure to secure the car exhaust from flexing before trying the wrench. I used wood to shim between the frame and exhaust. Crows foot didn't strip anything, and this worked where other sockets failed.

Appears to be well made

It arrived about a week after I needed it, but apparently that was USPS fault & Not Carnage. Anyways, seems to be well made & fit the 20mm nut well. But kept falling off of the 3 different extensions I tried it with. Apparently the reason being that there is no divet in the extension well like most sockets & crowfoots have to help keep them in place on the extension. So I used a dawb of heavy grease & it seemed to work for my use. Otherwise it seems to be well made & I also like the offset on the opening of the jaw which helps in placement on nut & strength of the wrench. Keep in mind this is a fairly thick & solid wrench, so it might not fit in some smaller areas, but is solid. The missing divet was my only complaint & since I still have the vehicle I am keeping the wrench for next time.
