KoKen tends to be my “go to” for these at present. Probably the best quality to price, and the variety available is amazing. Four different lengths, two different styles, plus impact (in two styles). They offer sets, but only on rails, not in a case.



Stahlwille are good, very tough, but if you do twist a bit they won’t sell you just the bit, only the whole socket. They do offer cased sets though.

Hazet are also superbly tough, and better finished than the Stahlwille I think. They offer two styles, of which I think the one piece (985) are stronger. Sets are available, and you can often get the set of 985 bits, in a steel case with accessories, on factory promotion.
The TiN coated 986 sockets are prettier, and probably more corrosion resistant.
