What Would You Call This?

I am looking for a part that is probably quite common, but I don't know what it is called.  It is 1/2" outside diameter, and about .4" inside diameter.  It has a shoulder on one end so that it doesn't slip inside the 1/2" hole into which it fits.  In this case, it is to enable a M10 bolt to fit snugly into a 1/2" diameter hole.  Of course, this is simple enough that I could make it by starting with a 5/8" piece of aluminum, turning most of it down to 1/2", then drilling a hole through the center.  But I am sure that this is a common item -- if I know what it is called!

    Thread Sert?
    Looks like a pop rivet. You can get the pliers and pieces at Harbor Freight.

    Drill bushing look for one with a shoulder

    Try "bushing" or "adapter".

    I'd call it a flanged bushing, but there's no way I'd even walk to the computer to order one, let alone drive to the store.

    And, of course, you do also. :-)

    Just based on your description, I would hazard a guess that would be a "shoulder bushing".

    Something like https://www.pegasusautoracing.com/productselection.asp?Product=3077-050.

    Best of luck!

    That sounds like a flanged sleeve or bushing.

    Thanks to all! While I could make it, I hope to use dozens to hundreds of them in the next year or so to satisfy a European market, and some things are more efficient to buy than make.

    Would a drill the size of an M10 bolt be a better solution for the European market?

    I guess that I will make it myself. The various items in question are either intended to handle high RPM (and are therefore somewhat expensive) or made of plastic (which might not survive very long). But I can buy 1/2" steel tubing pretty cheaply, and use that. The head of the M10 x 1.25 bolt will provide the shoulder that I need; I will drill and tap the interior of the tube so that the tube is held in place by the threads.

    what you describe, if the inside surface that is .4 diameter had threads it sounds like something I was looking for, and, I kid you not, I was told it was a "sex bolt."

    Try flanged threaded insert

    Um, if you're just using this as a filler, it need not be threaded. Generally, unless you're using jam nuts, you only want one threaded thing on a bolt.

    Yes, you are right, it doesn't need to be threaded. There will be a nut on top preventing it from moving.
