    I figured this would be as good of a place to ask as any as everyone else I've asked had no idea.

    Do you know if there exists anywhere a bolt where the head of the bolt itself has it's own female threads for another bolt? see picture.

    I had this idea that I could use these types of bolts (or screws) on the back of pedals then fasten/bolt the pedal down to a pedalboard through the larger diameter hole.

    Did you draw that?
    Sorry to say but it kind of makes no sense.

    Exactly what are you trying to accomplish?

    use the red part to replace the screws on the bottom of your pedal, now you're left with an extra wide post to fit into holes in your pedal board. then use the blue part to fasten down the pedal to the board.

    That's just a round stand off. Might be available. Check Digi-Key. If they don't exist have someone with a metal lathe make them.

    Those are the little screws that hold the bottom cover onto the pedal box.
    It looks like the holes will be drilled larger in the cover.

    You may be able to find something like that at a local hardware store or fastener retailer.

    There may also be studs, adapters (from one size to another) and nuts that could be used.
    There may be adapters with female-female or male-female conditions.

    I would rather not drill anything and use adapters to bolt/screw things.

    A standoff (stud adapter combo) as @Cadorman mentioned.

    Yes it's called a (female) sex screw. Or sex bolt, etc.
    And it is hard to find, only specialty hardware vendors carry those type parts.
    But yes there is such a screw and there are many different configurations both male and female.

    I found these. They would likely work if I A)I used a (lock) washer, and B) the threads matched the pedal.

    Guytron used those on their combo amplifiers. Most rigid cabinet I've ever encountered.

    Most Ace Hardware have a nice selection. You can go there with your existing screw and match up things that could/will work.

    A fasten retailer or bolts and screw retailer should have and even greater selection.

    Common metals, plated, brass, stainless and so on.

    The sex-bolts are iteresting but purchasing or maybe even finding something that will work could be a pain.
    Still definitely work a look.

    Seeing how you have to drill and tap a hole in your pedals for the sex bolt, why wouldn't you just just drill and tap the hole and use a longer bolt that reaches through your pedal board directly into the pedal itself?
    Most pedals already have a back that screws on, I would just buy the same bolt size # but longer.

    The sex-bolt would have to be small and match the existing screw in order to reaplace it. I thought that would be the plan.

    Normally you would use Velcro.
    There is military grade silent Velcro also.

    "The US military has a secret, nearly silent type of velcro which reduces the ripping noise by over 95%."

    haha......yea, I use velcro now, noise isn't a problem though. I'm not sneaking around in 'Nam looking for Charlie. I didn't know they had military-grade velcro though

    I know they also make that "mushroom" grip stuff but it's really expensive.

    screws & bolts seem like the best thing though

    Is this for metal or wood construction?
