It's been literally decades since I had to service a loose bearing hub properly.
This one came with a used 2015 HT and needed a service but didn't get used as a had a spare (better) wheel.
The loose bearings measure about 0.245" (6.22mm) so can I assume these are 1/4"?
The freehub screws into the hub and has a 12 star inner just bigger than an 11mm hex that will slip about inside. What's this tool even called?
Small bump
the tool is called an allen key, freehubs on loose ball hubs have either a 10mm or 12mm hex head hollow bolt that you can access once you have removed the axle

12mm won't fit...
11mm spins
Probably large Torx.
What bike was it on? Sounds like one of the loathsome Formulas...
Apart from double hex, the other 12 point interfaces are triple square and 12 point spline. In the case of triple square it would have 90deg points rather than the 120deg of double hex.
Can't think of a torx bit that has 12 points unless you're counting both the innies and the outies.
I've never seen a triple square on a bike. They're used quite a bit on VW/Audi Group cars. I think that a 12mm hex driver would not fit in a 12mm triple square. If the points look square then a 12mm triple square (or possibly a square bit) might be what you need.
They are normally removed with a hex bit, some from the drive side, some from the non drive side.
There are a few different 12 point tools
