model 11 bolt

I have a model 11 and I am trying to disassemble the bolt. The back end of the bolt does not have a place for an allen wrench or a screwdriver. I'm not sure how to remove the end screw. All the videos I have been able to locate have had either an allen or screwdriver.

The bolt needs to be decocked, to remove the Bolt Action Screw, move the cocking button, to the long slot on the cocking ramp in the bolt body. Should then see where 1/4" hex head wrench fits.

Thanks for the help.
