Review: These are nice, small lugs - I bought these for a set of Work Meister S1 wheels and so far like them. The lugs are impressively small and have a snug fitting key adapter. I have used a number of lugs before and these are probably the smallest I have seen. The diameter of the the outside of the lug (with the key on) is no bigger than the diameter of the 60 degree lug seat. This means it should theoretically fit in even the tightest tolerance wheels. These are spline drive lugs, so a standard lug wrench won't get them off. This likely provides a small degree of security by itself, though for expensive wheels I would recommend a good set of locks. I picked up the Gorilla Automotive 71631NBC Acorn Black Chrome Wheel Locks (12mm x 1.50" Thread Size), Pack of 4 . The finish will likely hold up well over time. This is due to the nature of the finish itself and the fact that the key fits very precisely and will not slip across the splines. I find that one of the main reasons regular hex lugs get scratched is ill-fitting wrenches which slip and slide across the surface of the lug. You will get none of that with these lugs. The key for the lugs has a section for a 3/4" wrench and one for a 13/16" wrench. I would suggest using the 13/16" since it is closer to the middle of the key, and is a larger diameter. This will put less stress on the key itself, reducing wear over time. Overall a very well designed set of lugs for tuner wheels.

## Questions & Answers

**Q: Will the black paint come off over time?**
A: I have the other style of Gorilla lug nuts (the specific key way with the short grooves) and even with use of an impact on the key to remove  them, they have not lost any paint. Not even in the grooves where the key makes contact. If Gorilla keeps up that same standard, they should stay black for a very long time. One set I have has been in use since 1997. The other vehicle has had Gorilla since 2006.

**Q: Are the spline grooves evenly spaced or do they have a unique pattern?**
A: They're evenly spaced.

**Q: Is the tool  included ?**
A: The key is included.

**Q: according to amazon these do not fit my 2012 kia sorento but according to the fitment guide it does. i just wanted to confirm whether they would fit.**
A: As long as your hub assembly stud size is 12x1.50 than these will fit, I have a 2014 mazda3 and that is my size too but yet amazon saying it dont fit? Weird must be website bug or something? It happens from time to time, they cant keep up with all their products info lol

Sleek lugs, nice quality

### ⭐⭐⭐⭐⭐ Good quality lugs
*by M***L on March 5, 2023*

Had these installed on my aftermarket aluminum rims and they fit perfectly, the tire shop was a mom and pop place that used air gun with no ft lb torque setting and the paint did not chip or peal, they seem strong and well built, just like oem feel. The tool to install the lugs also feels well made, I placed a piece of heatshrink over the tool to avoid scratching my rims if I ever need to tighten or take the wheels off.
