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 ## Frequently Bought Together - Gorilla Automotive 21133BC Small Diameter Acorn Black 5 Lug Kit (12mm x 1.50 Thread Size) - Pack of 20 - Gorilla Automotive 21631BC Black Chrome Small Diameter Wheel Locks (12mm x 1.50 Thread Size) - Gorilla Automotive 1921SDKEY Standard Small Diameter Lug Nut Key --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/1915190-automotive-21133bc-small-diameter-acorn-black-5-lug-kit-12mm](https://www.desertcart.us/products/1915190-automotive-21133bc-small-diameter-acorn-black-5-lug-kit-12mm) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-06-23*
