"Harder" isn't necessarily better. Stronger vs the TTY, yes. Metric grade 10.9 alloy steel would be the type of bolt that would be correct. 12.9 is stronger more but that would not be required. It was previously mentioned about never seeing any of the TTY bolts break. The first delinquency would be from a loss of clamp load allowing the eccentric to slip and lose the desired alignment. A yielded bolt will continue to stretch the more it is tightened. It may break then if it is a clueless tech who is doing the tightening.
One solution is to use SPL adjustable toe rods with their lockout bolt kit. That solves half the TTY bolt issue plus they make toe adjustments alot easier.
AFAIK, nobody makes a replacement eccentric bolt that would satisfy the lower control arm (camber) adjustment. I modified and installed a non-TTY Gen5 lower control arm eccentric bolt on my Gen6 but I want to pull it and examine it before I deem it successful. My alignment has held since I installed it last summer and the bolt itself has not moved.
Once any bolt has been yielded, or in other words, permanently stretched, it will not have the desired clamp load. Reuse at your own risk.
