Oh look at all these studs w/ their knurl area all sticking out
Here are the difference between all 3 studs that I got. The ones that came on the hub is on the right. The first batch of studs I got on the left, and the 2nd batch of studs I got in the middle
Look closely at the knurl area on these studs
So yeah, still waiting on vendor to email me back...
