cracked a ring gear bolt

thanks Cass. I am wondering myself. Because i used good new torque wrenches, all cleaned and dry, enough space under the bolt and definitly not overtorqued with 60Nm ( not even reached ). Most of the bolts are visible damaged ( became thinner in the middle, sign for to much stress ). I am just saying there could be something wrong with the bolts you've been supplied with. And off course ist my here in Germany who picked them... :)
