    Crank bolts

    Where can I get crank bolts such as this:





    Danscomp doesn't have anything like it. The bolt pictured is from my roommate's bike and they fit my new to me Haro 3 pc cranks but I cant find anything like it.
    When in doubt, style it out.

    Those are generally 3/8" 24tpi bolts, available at any hardware store.

    I forgot to mention that they are 6mm hex. It doesn't seem like a hardware store item but I guess it wouldn't hurt to check. To give some perspective:

    When in doubt, style it out.

    The head doesn't matter for the sprocket bolt; I've used non-allen bolts before without any issues for that application.

    If you look at it though the head of the bolt makes contact with the edge of the hole for the spindle. Its not like most road or mtb cranks that I am more familiar with where the bolt is recessed. A normal bolt wouldn't work.
    When in doubt, style it out.

    The server the picture is hosted on is blocked at my work, but I can't seem to picture what you're talking about. Do you mean that the head of the bolt makes contact with your bottom bracket shell?

    Oh. This whole time I thought that this was about the sprocket bolt for some reason. For that, just get a thick washer (preferably a machined bushing) and cover the whole end of the arm.
