I've just been looking at a well know kit car suppliers web site and just come across the rivets they sell ( 4.8x16 )
What the !!!!!!!!!!!!!!!!! are they using them for.
Any guesses ?
Ally floor panels
I hope not the floors are 1.5mm Ally sheet so the wall thickness on the chassis must tubes be at least 7mm thick...
engine mounts ?
Please No... 
Roll cage then 
Grip range on a 4.8x16 is either 6mm-9mm or 8.5mm-11.5mm depending on type.

so that's down to a 3mm floor with a 3mm chassis... hmmm
Has any one gone up to 3mm on there chassis ?
I suppose it would keep the C of G low...
8.5-12.0 Overall Grip Range On the one's they sell.

Too big even for wishbone brackets
Grip range depends on rivet type. If they are a multigrip type rivet (i think that's the name) then the grip range is a LOT larger than the
normal POP rivets...

3mm floor, 1.5mm chassis and 1.5mm side panel = ????
(why does everyone forget the side panel?)
A 3mm ally floor would weigh 10.7Kg 1.5mm would be 5.35Kg
I don't think i could afford to buy a sheet of 3mm Ally to make the floor with

Hi just as important are they sealed rivets. Or open that allow all the water in. That also helps lower the CoG.
Cheers Matt
No they are open ones 
I only use sealed rivets myself ( on all panels )
Want to give the chassis the best chance not to rust from the inside out.

Rivet lesson ,
rivets that have no access from the back to react them are called blind rivets .
made from two or three parts ,rivet mandrel and locking ring .
many different materials are used to make them but they all work in the same method .
imperial measurements diameter in 32nds and length in 16ths metric diameters in .1mm increments length in 1mm inc .
grip length is determined by material thickness and you usually follow rivet manufactures giud lines however we can do a small test peace to see if we
have a nice reaction,reaction is when you pull the mandrel through with your rivet pliers leaving a nice bulb shape at the rear of the rivet .
general rule to get the length measure thickness of the metrial you want to rivet then add 2 times the diameter .
this should put you around the correct length but do a test piece it goes with out saying that get the correct drill size.
i recommend when you install the rivet that you put a small dab of sealant the stuff you used to put on your body panel this helps to keep out the
moisture .
There are rivets that the mandrel breaks off flush with the top of the rivet if you do get hold of this type of rivet .then you must be precise on
your length as the mandrel relies on this as its point to break flush with the top of the rivet .

yes that's correct .like i said do a test piece first and use the correct size drill your looking for a transition fit with the rivet . measure the thickness of the material this is the grip length add the approx 2 dia this is the reaction .
