Ender-3 corexz: no nozzle throat set screw?

My nozzle is clogged and the normal cleaning procedure didnt’t work. So i tried to remove it for cleaning.

I used the procedure described by the video “Service Tutorial Ender-3 V3 Replace the Nozzle” linked in the ender3-v3 section.

The video states after heating up and before unscrewing the nozzle i should “Loosen the nozzle throat set screw” - but there seems to be now screw in this hole - at least none of the supplied allan wrenches catches?

I think it should be a 1.5 allen key, that is if it is an M3 grub screw. If it is an M2.5 then a 1.3 allen key.

Got it - i overlooked the second smallest allen key. This one worked.
Thanks,

Did you figure out what size the screw is ? I seem to have lost my nozzle throat set screw and trying to figure out which one it is to purchase.

The second smallest allen key fitted, so according to Bonfireman it should be an M3 size.
