Has anyone succesfully purchased just the HANs posts from anywhere?

The posts meaning the actual bolt / post that the tether clips to,
You know the ones with the eeentsy-weeentsy flat spots for a wrench and a none to deep (and curved) slot for a screwdriver?

I have succesfully mangled mine swapping over from my old helmet to my new one and wondering if I am going to have to buy two anchor kits just to get these little posts.

Anyone else mangle theirs?
Are they intended to self destruct after one installation or am I just a clod?

Thanks in advance
