    Washed the M3 last evening in the driveway. This AM my wife found this in the spot where I washed the car. I'm not sure if it came from the M3 or not. Anyone recognize this part?

    Man that’s a strange looking bolt I can’t imagine what it’s used for in a car... you buy any furniture or something decorative

    Nope, no furniture. I don’t recognize it all and don’t own an Alpha Romero:)

    Did have a friend with A BMW over last evening but they weren’t in the driveway.

    Oh well, will keep it around just in case.

    I thought this was going to be an off-topic thread about a Chevy Bolt. I was disappointed when it wasn’t.

    New type of tamper resistant / anti-theft security bolt?

    edit: No, scratch that. Looks like you could put a standard flat screwdriver in between those lobes.

    edit2: Nothing in the McMaster-Carr catalog either.

    I thought it looked anti-theft-ish. Also decorative. Like something that would attach a license plate.

    I’m stumped which isn’t all that shocking.

    But when the internet is stumped, that’s a rare day :p

    @Wnuk Can we get some dimensions? Overall length, screw diameter and screw pitch would be nice too if you can determine it.

    My first thought was something for a camera mount but those are usually a bit longer. The threads looks like 1/4-20, but could also be 3/8-16 so that's why I'm asking for dimensions.

    not an automotive part.
    if automotive, it would have phillips, hex, torx or allen head.

    @RayK Overall length is 1/2 inch. Thread length is 1/4 inch. Diameter is 1/4 inch so I assume it is a 1/4 20 thread.

    The head is puzzling as that is a pattern I haven seen on anything else here at the house. A flat balde screw driver would be difficult to use on it. And I’m not aware of any tool with a pattern like this.

    I checked all the small engines I have and none are missing an oil plug. Nor is any furniture missing a leveler on the feet. All vehicles have license plate brackets mounted properly.

    The mystery continues.......

    Material? Aluminum - maybe motorcycle billet. Stainless - maybe marine. Chrome plated - maybe auto
    Too shallow for a license plate fastener. Sheared?

    May have come off the wash bucket or power washer that you used to wash your car that night. The part does look more decorative than structural.
