I just bought a used set of socket wrenchs. It has both 6 and 12 point
sockets. Why?

I am guessing that 6 is stronger and 12 can be used on square heads, but
neither of those seem to justify having both. Is there a better reason?

6-pt are, indeed better for really stout needs as there is more
surface area so lest likely to round over a head or break or strip the
socket if need really high torque. 12-pt is slightly more convenient
in use as they line up at twice the locations of 6-pt.

Neither will fit square head except by happenstance -- need 4- or 8-pt
for that. Which, btw, are getting extremely difficult to find any
longer..
