Opinions needed from experienced metal workers Re threaded fixings

Now, are these standoff type things pressed on or do they have a glue holding them on.

I believe they are pressed on as there is no sign of glue or anything, maybe some kind of weld?

Do you think they are pressed on? There is no marks on the otherside of the metal to indicate this tho (normally a good sign).

The marks around it seem to be from where its pressed on i think. its around most if not all of them

there isnt a hole on the otherside of these things tho?

I dont want to fit them, i just dont want them falling off in the acid bath before anodising. If they are attached by pressing then they will be fine, if they are attached using some kind of adhesive or weld they may come off

lol i didnt look properly , then my guess is that they are spot welded on , if you do drop them in an acid bath , im presuming your zinc plating ot chroming then you could always glue it on afterwards after taking some measurements of its exact position

Im anodising

.

there are about 50 of these things, i dont want to be gluing them on in a hurry.

plus if they fall off i wont get them back

they could be friction welded ?
...I can't tell from the pics

good point, would explain the markings around them and small amount of "debris" that is on the bottom edge
