Spanner for headset bolt

Is there a special spanner I can get for a headset lock nut or do I just use a large adjustable spanner?

you can
i have one, however it was weak and a bit out of sizing and put marks in the nut (cheap bike tool)

i then used a shifter with greater success

Whats a shifter!?

For the top nut, an adjustable spanner (a.k.a shifter) is fine - though you would usually use headset spanner to hold the lower cup still while tightening. With a bit of trial an error you can back off the cup a little and allow for it to tighten if you are just tightening the top nut. If you have a notched streerer and matching tabbed washer, you should be fine.

That’s a right handed one. :stuck_out_tongue:

aren’t you cute

Not really…just a retarded pom.
