where is best place to find these?? due to my wheel and 15mm spacer i need 60mm of thread and i'm struggling to find any longer than 30mm? the ones i currently have are 50mm thread but they only seem to go into hub 10mm which doesn't seem enough and may be the cause of my wheel coming off??
The thread intrusion into the hub only need be the same as the diameter of the bolt. ie, if the bolt is a 10mm width then it only need go into the hub 10mm. Any further and you don't gain any strength, you just turn the wheel nut wrench more.
