Reaming recess in Hi Lok pins?
Reaming recess in Hi Lok pins?
(OP)
Has anyone run into reaming out the hex recess in the tip of Hi Lok pins during installation? We have not installed these before and my boss is worried that he is going to see that as a failure mode.

Hi-locks are generally an interference fit.
It shouldn’t tend to spin in the hole while the collar is snapped.
When it does spin, you should probably consider re-drilling to the next oversize and try again.
I understood that the act of driving the pin into the slightly undersize hole was to intentionally work harden the inner surface.

Installers come up with new shortcuts every day, but not using a hex recess is a new one. Shouldn't spin and can't spin are two different things.
