IMO using 6 point Allen bolts is a mistake. In my experience the allen heads strip much easier than the 12 point triple square bolts. The triple square drive was designed to handle more torque than the older design of the allen heads.

The key to being successful with either style bolt is cleaning the heads of the bolts out so the tool fits all the way in so you have full engagement. Also make sure the threads on the bolt and in the bolt hole are clean when you assemble them. And use a torque wrench to get the correct torque on them.

The safety wire is a very good idea but kind of a PITA to wire them.
