name and reference screw type

[davideb88]

Hello everyone, I am engaged in the writing of my graduation thesis and at this time I would need to identify the type of lives that you can see in the attached images. I have to find its reference online and possibly a supplier and its measures. the step file then would be the maximum.
Thank you very much

I don't see any lives, but only a record with something confused in the center.
it takes an entire image of the screw, details of the peculiarities, a context in which it is used

There is no shadow. in the middle of the fusco there is a piece that can be a male or female pin with ring put to screw and unscrew and then fold to not make bulk.
It's not normal. There's gonna be someone who's doing them in series. Maybe it's part of the product and then made to special design and you'll never find anything. first imagine how it is done and draw it.

It seems like a nut for locking discs grinders or similar things.. but there is no reference and no tools to screw it-----> look here

thanks to all of the answers.
under the link to a video to better understand the operation.

thanks to the answer, I hoped it could be a piece made in series at least so that I could mention a real product in my thesis. Thank you.

So let's see if I understand: instead of making decent screenshots, accurately describe where and how the screw is used, you preferred to make a 2-second video and whose preview is one of the above pictures, video that to see it you have to record at the site on which it is loaded.
Good strategy.

try to look in these pictures, maybe you find something, difficult though it's something normalized.

Hi.

these images with shadows, blur the identification of the object.
However I do not see an internal thread, but a disc, type ceiling, with the central hole (for the passage of cables), and a bent and welded washer for the support of a hook.

or maybe they are screws at 1/4 round or dzus. those to put and quickly remove the hulls in the motorcycle for example. Boh...
