Look over this set of silver (not chrome) lug bolts with radius seat. Shank length is right and the hex head looks like the OEM version. If I were using the center caps, the silver lug bolt would be sufficient for me.

The OEM lug bolts on my 2007 Coupe are not threaded the entire shank length. Threads probably only cover the bottom half of the shank, which would be sufficient for torque loading. Most after-market lug bolts have threads the entire shank length. Curious why they do that?
