1/2 Inch Drive x 21 mm 6-Point Impact Socket | SID23121 | Deep

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.

Helps a lot, good quality.

Good product got here quickly

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.

Carelessness required I spend more money. This was worth it.

Good tool, been taking a beating and has not stretched or failed, grips the nuts tight and i have not rounded any off

Very good socket quality is very good and it worked very well and I’m still using it. Don’t miss out on this nice product that works very well. You could buy it and not be sorry that you did because it works perfectly.

Very good

Great deep socket for wheel nuts.

1yr later and still using this almost everyday, great quality!
