Pop rivet sizing

Hi.  Not concerned with the diameter of a rivet head for different strength required (as this is for two parts of a petrol cap) , though is there a rule of thumb, ratio, for the length, IE, for example, if X thickness of metals to be riveted, require X length of head.

Cheers, Dave

Hi Dave ,

 if you were using solid rivets then the material thickness to rivet length ratio is important.

Pop rivets this ratio is less important as the rivet is not truly a structural fastener.

However if you look at Pete's link then you may see that the rivet length is material  T + the rivet shank O/D. 

EG using a 3.2 diameter rivet  with  4mm of material then go for a 7mm long rivet or the next size up.

You don't want to use a 20mm long rivet in 4mm of material.

I sometimes custom make the pop rivet if it’s to long, tap the rivet off the stem/nail saw to required length ie the of material plus a little protrusion (say 1/8in) quick file of the cut end put the rivet back on the stem the right way and fit in hole and pull up, all nice and tidy

Ahh! "pop" rivets. Choice of sizes, and lengths, then colour coded as to shelf life and usage. Bless The UK Aircraft Industry. I have several hundred, all of which where declared as "scrap", having not been used in the time scale. Same applied to the Solid rivets too. Ok for General/home use though.

It's a 3 prong/filler neck locating part that was riveted to the inner part of simple petrol cap. Have the usual rivet sizes, though too big.

To redrill the 2 holes for common smallest rivet, would make one of holes very close to the edge of the locating section and be a weak point I reckon.

Likewise the Bus Industry; I have friends who work on buses and they have tons of obsolete fittings, including rivets in all kinds of metal and sizes including aluminium. I'm always calling in on the scrounge!
