    Thru-Axle Reciever Bolt?

    Is that what it is call? The nut that the thru-axle screw in to. My new frame and wheelset combo didn't include the nut at the rear derailleur hanger. Seller is ignoring my inquire as of now. What is it call? Any good source for online order? It's a DT Swiss C 1800 wheelset (12x142mm) and I'm assuming it's universal?

    It's called a nut AFAIK, a pic of what is missing might help.

    You could also call DT in Grand Junction and see what you can figure out, re: if the frame manufacturer sources it from them.

    It fell out of the frame?
    I never even knew there was a nut in there, I thought the frame droppout was tapped.

    Axles and nuts aren't specific to wheels, they are sized to the frame (and like others, never heard of the nut falling out).

    I agree, the OP should be contacting the frame manuf to get one that fits. Just any old nut just isn't right!

    It's 2020...can't you manage an in focus close up? You're gonna need to get in touch w/ the frame seller, DT has nothing to do with this.

    Likely nothing is faulty, you're just missing a part that should have come with frame (not wheels).

    This is almost 2021, and everyone that has a phone thinks it's a camera. It's not, it's a piece of sh*t!

    Depends on the phone. Mine actually takes pretty good photos.

    To the OP: If you provide more light on the subject, a closeup will focus better.

    Looks to me that the recess there is designed for what we call a "Double -D capture nut". Looks like it would be specific to that frame manufacturer.

    there's a fair chance at least 2 pieces are missing, the nut we are all talking about and possibly a smaller screw that keeps the nut in place so it doesn't just fall out when you don't have a wheel in place. If they only send you the nut, but the nut looks like it has taps where a screw should keep it in place (or if the frame has a place where such a holding screw should exist) keep an eye out for that.

    wow I've never seen a frame where the nut just can fall out so easily like this. For all frames that I've run across, this nut is usually permanently fixed in place. Imagine you're on the road/trail and you take the rear wheel out and this nut go rolling off into the bush. ugh.

    Hoping that it wasn't a fixed at the factory rather than it fell out before boxing. The frame and wheel set came in a standard bike box with no visible trauma.

    you should get an extra nut then. Somehow I get a feeling you'll need it down the road. It's not like you can just go to some hardware store and buy this nut

    It's not uncommon for the 'nut', or 'receiver', or 'threaded insert' to be separate and not built into the frame. It's the same concept as a derailleur hangar. It's a disposable/replaceable part that you can replace if it becomes damaged.

    As mentioned, these are proprietary to each frame, so it's probably worth collecting a spare or two, just like with derailleur hangars, when the bike is still new'ish and the parts are easier to source.

    Every thru-axle bike I own has a separate 'nut' to receive the thru-axle (Moots Routt RSL, Canyon Endurace, Norco Search XR, Trek Domane).

    I think my old RoadMachine may have had the threads tapped into the dropout, but I can't recall for sure.

    A couple of examples.

    It's usually a separate piece, but I think also usually there's a way to secure it to the frame. Really curious to see what this one looks like, OP can you post a picture when it arrives?

    Sucks to have to wait for one piece in the mail when you're trying to do your bike build. Recently got delayed for 2 weeks waiting for a derailleur barrel adjuster. The person who gave me the derailleur had kept the part in case he needed it for his conversion to eTap.

    How do you know he doesn't have airplanes flying into his derailleur.
