Please pardon me for these newbie questions. Could anyone clarify for me the dimension referenced for size? For example, when zenith says 5/32" rivet is the dimension reffering to the diameter of the rivet that passes through the material to be fastened? 

Is a different size head required for each rivet size to accomodate the difference in stem diameter?

Has anyone had their own riveter head domed, or did you have to buy them?

Does anyone know the textron part number of the rivets? I look at the textron fasteners website looking for a data sheet, but the numbers they use are not simple "A4" or "A5" and their names aren't just Avex, there's Avdel breakstem systems avibulb blah blah blah. I'm just trying to get the data sheets on what will be used in the kit.

Thanks for your trouble.

    Hello Today I called Zenair (in Ontario) and obtained the part number for the rivets: A4 (1/4") 01604-00412 A5 (5/32") 01604-00514

However, I intend to acquire new batches exclusively from ZAC. It's a long story, but the short version is, you can't go wrong with ZAC rivets.

For the long version, search on "rivets & china".

The stated size is the diameter of the rivet before it is set. The hole 

drilled in the metal will be slightly larger (#30 for A4 and #20 for A5) 

to allow easier installation. The rivet will expand to fill the hole 

when it is set.



You will need a different riveter head for each size rivet for the 

reason you stated and because the dome cut in the head will have to 

match the size of the rivet head.



Machining the dome into the riveter head is not difficult. I just 

chucked the head in my drill and spun it while grinding the dome with a 

grinding stone in a dremel tool. Grind a bit, pull a test rivet and 

grind some more as necessary to get a good result.

Hi Craig;

   

  Anyone asking questons is an asset! I have had very good results calling ZAC - they always answer very directly.

   

  The aircraft rivet callout always refers to the diameter first and then length - however, I have never used these rivets so do not know if it applies to them as well. The diameter is in 32nds and the length is the grip length in 16ths - usually!

   

  I have attached the PDF for the 1604 fastener (that is what they said it was).

Thanks for all of those who took the time and effort to dig up information for me. I have all the information now. I will need 2 heads for my puller, I can modify them my self, and I have the data sheet for the specific rivet type used. I had suspected it was the 1604, but wanted to be sure, not guess.

Looking forward to this project, just waiting for Can-Zac to schedule the next rudder workshop to get started.

Any other 640 builders out there?
