JB Weld is not a strong epoxy. It's an ordinary amine-cure epoxy
that's filled with steel powder, and its strength is typical -- less
than 4,000 psi under ideal conditions.

They make some wild temperature claims for it, but my guess is that
they're talking about the temperature at which it breaks down and
begins to carbonize -- 550 deg. F. It's lost all useable strength long
before you reach that temperature.

JB Weld outperforms West System where high temperatures are concerned.
OTOH if I understand the question I would also vote for the 6xx
retaining compounds (Vibratite make Loctite equivalents and are
cheaper). One thing to note: They hold differently on different
metals, e.g some are weaker on brass than on steel. The data sheets
are useful here.
