I have found more horrible Torx cap head screws - big ones for which I don't have a key. I don't understand the sizing - the biggest I have in my set is T40 - which are 6.5mm across between points - so how the heck are they sized ? 40 what, gnats crotchets ? I suppose I will have to buy some more bits, but I need to measure these so I buy big enough.
