Review: 3/4" no. 19mm - I just got these today. I didn't notice these were 19mm, but felt reassured when others said they were 3/4" also. Can you use a 3/4" on a 19mm? Why, yes you can. Will, you have to tap the socket loose to get it off the nut? Why, yes you will. Otherwise, these look very nice, and the chrome seems to be applied well. I'm replacing the old ones that were on my wheels for 30 years and are rusted. If these last that long, I probably won't even care.
Review: Quality and durability seem good - Accurate description and nice quality part. Style of the lug nuts fit well on my aftermarket wheels. I tried using both 19mm and 3/4” sockets to tighten and both sizes fit nicely so you could use either one in my opinion.

### ⭐⭐⭐⭐⭐ Quality and durability seem good

Accurate description and nice quality part. Style of the lug nuts fit well on my aftermarket wheels. I tried using both 19mm and 3/4” sockets to tighten and both sizes fit nicely so you could use either one in my opinion.

### ⭐⭐⭐⭐ Tap them before use!
*by A***R on May 15, 2024*

They work well, I would just highly recommend using a tap and tapping the threads before use because it appears that these are dipped when painted allowing paint to adhere to the internal threads which may allow you to get 3 threads on or so, and then it gets tight. I have the black version on these lug nuts (And yes, I'm positive that I have 7/16-20 threads)
