ooo something similar but less bulky
when I was fitting sleeper cabs to trucks we had a gun that inserted a metal sleeve then the gun withdrew the thread the sleeve was on and so tightened it inside the body and crimped it inside the body..this was then super tight and you could use whatever was the right size bolt
if I figure out what it was called I will revisit the thread..it would have been ideal for this
