    PS to PS adapter bolts

    I got a Shimano PS adapter to use 180MM rotors, I realized the original bolt are too short
    Can a metric bolt from hardware store do the trick, does it need to be allen head or hex head is OK? do I need a lock washer?
    Is it easier to find at a LBS?

    Or does it need to be a cyro'd, shot peened or drop forged bolt

    Yes a metric bolt from a HW store will work. I suppose you could use a hex head, but it should be easy to find a allen head. Try to find a stainless still bolt if possible so you won't have to worry about rust.

    Washers aren't absolutely necessary. I don't use them and never had any problems.
