Cleaning jetter nozzles

[Aussie Plumber Greg]

Recently I started cleaning my jetter nozzles more regarly and tried to clear my warthog and as the nozzles have a hexagon .
I was wondering do you undo that nut ,butthe only trouble is my socket wont fit in to hole.
I have tried using the no 5 drills similar to the one you use to clear oxy/acetylene tips but was wondering if the are other suggestions.
The line hasfine filters in them so it doesnt happen all the time.
