rivet question

[2nd District]

I have a question on the rivets used on the vent windows during the process of replacing the rubber. the rivets the resto companies (brothers, lmc etc) are what ive been using and my question is does anybody have a source or a part number or a place where these rivets can be purchased in more of a bulk manner? like 50 at a time for instance, and not the small amounts offered by these companies? the rivets seem to be 5/32"body diameter, 9/32" length, and 1/4" diameter head. Ive searched some rivet companies on line but cant seem to find this combo anywhere, any help would be great thanks

Those are know as a " shoulder rivet " if I'm not mistaken. It's always good to have your search terms as specific as possible, it narrows down the search results from infinity to just a few thousand.
I need a couple myself. I found some on a truck part dealer a while back so I know they're out there. Wish I could remember which one.

My ace has a couple of the Hillman drawers of split and shoulder rivets . I buy a few as needed they don’t have the stepped ones for the vent window pivot but I buy a few when I order other parts for the truck .
