JCLC Thomasson wonders:

<< Why are the CV joint bolts multi point when the
hex that fits is of course 6 sided?  Is there a tool
other than a hex to get the job done?>>

Yes, the tool for that job is called a triple-square.  As
you have found out the regular hex or Allen will strip
them.  The CV bolts are 8mm.
