I've actually been thinking this for a good few years now, just never thought to ask. Why do discs (brakes) use torx rather than hex? - I've had 1 or 2 bad experiences with torx, especially with rounding off, personally I think they're just too weak.

Does anyone else find this?

    they give a great resistance to rounding than allen bolts. there is also a little more material in connection to the shaft making then stronger.
    the use of the correct tools rather than the poor ones provided makes a big difference to the life of any fastener.

    Also they are much lower profile than hex bolts which means you have clearance between the fork leg and the disk. Allen bolts would chew lumps out of your fork!
