Rivet Callout

Rivet Callout

Rivet Callout

Hello all, I'm new here and have a question:

I need to decipher a river callout on a drawing, and I'm unsure of what this symbol is.

I have a series of rivets, and pointing to one of the holes is  cross with 4 quadrants. Is there a standard or publication that explains this?

The cross contains:
Upper left: B1
Upper Right: 5N
Lower left: C
Lower Right: 5

Thanks in advance.

RE: Rivet Callout

I'm not sure what the official standard is, but here is what I have become accustomed to using:

Upper left: Basic Code (there should be a block on the drawing defining these)

Upper Right:  Dash No. for Diameter; N = Head Near Side, F = Head Far Side

Lower Right:  Dash No. For Length

Lower Left:  D = Dimple, C = Countersink

RE: Rivet Callout

Beautiful. That's exactly what I was looking, thanks a bunch.
It's been a while since I've looked at a rivet callout, I didn't even know where to look. ;)

My sincerest thanks.

Here is a website that is wealth of information regarding the subject of rivets.

NAS523 is the spec you need.  It will decode the upper left corner for you.  

RE: Rivet Callout

So is that website and the spec riveting reading?

Sorry, couldn't resist. smile

My neighbor works one of the machines that makes those rivets. He works a lot of overtime.
