What grade are the 50mm torx bolts that hold the knuckle on to the lower control arm? Also what is the reason for the torx bolts,can we just use the proper grade bolts with washers and nylon locking nuts?

I messed one up so I had to do that on one of my old marks, never became a problem. I threw a grade 8 bolt and a ny-lock on it.
