## Questions & Answers

**Q: Will this fit a 14m? My truck has m14x1.50 locks**
A: Thank you for your question! Unfortunately, the Steelman Pro 78540 6-Spline 45/64-Inch Locking Lug Nut Socket will not fit 14mx1.50.  In order to determine what will fit your locks, we would need the size and the pattern of the lugs.  Please let us know if we can be of any further assistance!

**Q: Is the 6 spline 45/64 bigger than the 6 spline 13/16?**
A: I don't have both here to verify physically but 13/16 = 52/64  and this is larger than 45/64

So I'd have to answer: No the 45/64 is smaller than the 13/16.

Hope this helps

**Q: Will this socket fit a 17mm 6 spine lug nut?**
A: Hi Jessica, thank you for the question. The 78539 has an inner diameter of 41/64” this equates to 16.3mm. If you by chance, have a 2012 or newer Mercedes S-class that you are trying to fit this onto, we recommend the STEELMAN LT5110 17mm Star Shape Deep Impact Socket for Mercedes S-class you can find it at this address. https://www.amazon.com/dp/B01JC1KD5E Thank you!

**Q: Will this fit my 2009 Honda Civic Ex?**
A: Thank you for your inquiry!  Unfortunately, due to the potential for after market parts, we cannot say for sure that this will fit.  As long as the lugs on your vehicle meet the 6-spline shape and 41/64-inch size, this socket will fit.  Please let us know if we can be of any further assistance!
