## Questions & Answers

**Q: Is thi compatible with M12x1.50 Hex size 21mm.?**
A: I’ll just be honest I didn’t receive the tool that comes with product but the dual fitting should be 19mm and 21mm as a standard.

**Q: Those lug nut wont rust inside&outside?**
A: Use anti seize or if you're cheap use "clean" axle grease. Torque to specs (actually use a torque wrench).

**Q: Will they fit on s 2008 honda accord?**
A: The lug nuts will fit the car, but you need to make sure an acorn style lug nut will fit the wheel you are putting on

**Q: What is the overall diameter of the nut**
A: Regular diameter of any lug nut. However I don't recommend them because the inner cavity the key goes into, stretches and rounds out within 1-2 times of torquing them. I sent these back and just bought some quality gorilla lug nuts
