ASME Rivet Callout?
ASME Rivet Callout?
(OP)
Is there an ASME Standard for calling out rivets on a drawing? I have no experiance with rivets, our company almost never uses them but we found an instance where it is easier and cheaper than spot welding and now I need to figure out how to spec them for our vendors.
Thanks for the help.

What specifically are you asking about?
Are your asking if any notes are needed in the assembly drawing in addition to the rivets being in the parts list/ballooned or are you asking about the rivet holes etc?

The piece parts need to have the correct size holes in them.
On the assembly I'd just show the rivets on the drawing, balloon and add to the parts list.
In the parts list I'd put the standard the rivets are to (I'd guess MS or AN) or, if not to a standard, then an adequate description of the rivet.
However, if you can get a look at the standard GDTGUY gives that would be best.

How did you tell the shop that "a rivet goes here". That is really all I want. The shop is already putting the rivets in and I don't really care what they are as long as they are flush on one side.

But what verbage was used to say I want a rivet?

Unfortunately no, our sheetmetal parts don't get BOMs, for PEM fasteners and in this case rivets we just spec the part on the drawing.

Back in the UK the rivets were shown on the assembly drawing, same way you’d show screws or bolts. Given that many of the drawings I worked were old, pre-CAD, they were basically just circles. For CAD we sometimes had models that were just the head of the rivet with perhaps a very short shank.
There was a balloon to them with a number corresponding to the entry in the parts list.
That was typically pretty much all.
In the event you had a view that showed the deformed head of the rivet you’d just put something that looked pictorially correct, no great effort to accurately show the level of deformation etc.
The actual holes were as far as I can remember always detailed on the piece parts. This was even true for drill to match patterns although these were old drawings to BS standards and I’m not sure this would fit the current US standards. If I remember they’d have some theoretical location of the rivet holes given that corresponded to the position on the mating part. Reference would be made to the other part, something like “10 holes dia .125/127 to match holes in part XXX-YYY”.
This is from memory though so take it with a pinch of salt.
