Hi Zafatenko,
You can re-attach it but first you need to disassemble the screwdriver:
# Unscrew the knurled portion from the smooth black section of the driver handle. (You can apply heat to the knurled section where they thread together to help soften the threadlocker.)
# Once those two pieces are disassembled, run a 2.5mm hex through the smooth black portion to screw the brass post back into place.
# After that is reattached, reassemble the driver. (You can reapply the threadlocker if you wish.)[br]

I hope this helps. Happy fixing!
