Works Perfectly for Mustang Wheel Installation
I needed a 21 mm socket for installing the new wheels and tires on my Mustang, so I picked up this TEKTON 1/2-inch drive 6-point impact socket. Performance It worked perfectly with both my impact wrench and torque wrench. The 21 mm size fit the lug nuts properly, and I had no issues installing and tightening everything. Feel/Quality The socket feels solid and well made. The 6-point design gives you good contact on the lug nuts, and it handled the job without any problems. Limitation I haven't found any downside to it. It's a straightforward socket, so there isn't much more to say. Conclusion If you need a 21 mm impact socket, this one did exactly what I needed it to do. I used it to install the new wheels and tires on my Mustang, and it performed perfectly with both my impact wrench and torque wrench.

Nice quality scoket
Perfect fit and withstood my impact removing 2 rusty axle nuts. The thin wall allowed me to access the nut completely.

I won't know until I remove my tire
Had a Toyota, so I got the 21mm. Sold the Toyota and now I have a Honda, so I got the 19mm. Fits perfectly! Leverage is great for removing lug nuts that got impacted on. I have a 1/2" drive breaker bar, extension, and deep socket. Hardly takes up any space in my trunk and changing a flat tire will be super easy now. The 19mm deep socket fits well and won't rust. I think.
