Depending on size you might find that even Bunnings have them. I have recently purchased 5-3 and 5-4 sealed pop rivets from them, and they had various styles besides the usual truss head, including countersunk and large flange pop rivets in a limited size range. If you have a particular need, think about who else might use similar rivets. Roofing specialists, caravan repairers and boating businesses all use pop rivets of various styles and perhaps one of them could help you out, or at least give you a lead as to where you might purchase what you need.

Our Bunnings supply only one brand of rivets, OTTER. I rang Otter and they didn't have a clue about extended mandrel rivets.
Also tried the only local major players, Prime, Heatley, Konnect, again, no clue.
Living regional in W.A. is real pain at times.

Considering how rare these seem to be what are they normally used for?

Well I have no idea about the application of an extended mandrel blind rivet, but am as curious as SnapATap.

I did find a Catalogue from Goebel Fasteners Inc. and it described a heap of options for blind rivets - rivet material, mandrel material, rivet style etc etc On page 5 they did offer to make rivets with a longer mandrel as one of a number of specialist options for customers wanting to order them. From this I assumed a longer mandrel was not part of the standard variations on offer.

In Melbourne I have been able to purchase some useful rivets from United Fasteners ... for me that is aluminium rivet with aluminium mandrel to stop corrosion issues, and stainless rivets in larger sizes than the stocked by the green shed. I have been tempted to get some countersunk head rivets . Looking at the Goebel catalogue I will now be asking for some of the semi-structural rivets - Go-Bulb or Go-Inox -- I frequently place a washer on the inside prior to setting the rivet to stop the rivet pulling out of sheet material -- the semi-structural sort seem to create a large clamp in the inside without needing a washer

I remain curious about the application of extended mandrel bind rivets.

Thanks David for the great link to the Goebel's cattle dog

If you’re backing a riveted joint with a washer to prevent it pulling through the joint is designed incorrectly, rivets shouldn’t be loaded in tension.
You may find it difficult to source Goebel products in Australia, Avex do much the same stuff and are more easily found in Australia

I too am curious as to what the application is

I plead guilty on the poor joint design, but in my defence I am usually the mug trying to repair a problem or a break so it lasts a bit longer. Having looked online I see something called a "peel rivet" and wonder if it is what I could use for tacking things back together link to United Peel rivet?

Also worth looking at the triple claw or TRI GO rivets for distributed load sharing on p52 of the catalogue. A camper trailer we used to own used similar rivets on any fibreglass parts, and we never had any issues with them despite the outback conditions we subjected that camper to in the years we had it.
You are not on your own in using washers either, my hybrid van roof which I am currently working on to repair a water leak into the roof space, used lots of them when made. They also used steel rivets against aluminium which have rusted and let water in. Unfortunately the roof had glued down flexi solar panels fitted, not sure if by manufacturer or previous owner, but water got under the flexi panels and the pop rivets in that area severely corroded, in some cases to near complete extinction. The entire roof space filed with water, 3000x1760x20 mm, but the sealing on the ceiling layer was good and no water leaked in. I really only discovered the problem when diagnosing the issue with a lack of solar power, (the panels had failed) and when removing them discovered the state of the roof under the flexi panels.
I had also had a problem with the lift struts on the pop top roof, not coping with the weight of the roof. New and slightly upgraded struts had not made a significant difference but when I found that I had a roof full of water, that explained a lot. Work continues and at the moment I am awaiting some strengthening ribs being laser cut from 4mm 5000 series aluminium. When fitted I plan on having a one piece gell coat layer to replace the 3 piece +2 cover strips of aluminium sheet originally fitted.
It is keeping me off the streets and out of mischief in the meantime .

These rivets are for use in long nose rivet guns (which I do not own) for use in hard to reach places (which I do have).

I intended to use a couple of small nuts placed on the mandrel as I only need an extra 8mm of reach and less than 100 rivets for the job.

The pic shows an aluminium channel below the surface of two boards, with a steel tube below the chanel (not visible). (Channel to be riveted to the steel tube)

A std rivet gun nose will not fit down in the gap far enough, but with two nits on the mandrel, the nose does reach. Problem is that std mandrel is too short and the grip in the gun just grips the last few mm of the mandrel and rips it off.

It has become such a pain in the behind that I am going with screws instead, which I hope will last me out as removing them if they rust will be a real problem. Drilling out aluminium rivets would be so easy in comparison.

It really surprises me in this day & age, just how many things are available overseas but not in Australia.
A few months ago I tried to buy a particular plate rack for storing plates vertically in a caravan cupboard, not available anywhere in Australia, common place item in Target USA, unheard of in Target Australia, so I had to pay $30 freight on a $6 (USA) item from Amazon. Forgive me, I digress, and I guess I should be grateful that we can still get toilet paper from the supermarket, despite the best efforts of Chinid-19.
