I needed to replace wheel hubs on my 2004 Jeep TJ and they were OEM 12 points to remove PITA. I soaked the PB Blaster, heated it with a small torch, hit it with a hammer to loosen it, and still took off two out of six. I found them by accident but the large 6 point head is exactly how it should have been from the factory. When using a 6-sided key, the probability of their rounding in the future is zero. If you do pull hub bolts, buy them and keep them handy to put everything back together.
