A friend presents me with an assortment of rivets and a shrug of his
shoulders, so I'm attempting to determine what I have.

An examination of Table 7-10 of the AC shows head silhouettes; not
diameters, just shapes. Most of these rivets appear to have the
universal head shape (MS20470), but come in different head diameters;
for example here one with a .15 diameter, another with .185 diameter.
so there appears to be something missing in the description - *head
diameter. Spruce sells AN470 with a .250 diameter head.

Does anyone know how head diameter is taken into account? If I knew,
I'd know what rivet set to look for.

Taking the example from another direction, I have a rivet set marked
"T101E1-12" . GOOGLING got me no where. I could measure the detent in
the rivet set and imply a rivet head diameter, but without knowing how
head diameter is taken into account, I can't order a rivet set. Anyone
know how to cross reference rivet head size to a rivet set? - Mike

Is there any other marking on the rivet set? The ones I have usually
have some reference to the type of rivet and size. i.e. 470-4 or 4704
is for an MS20470 or AN 470 #4 rivet with a 1/8" stem diameter. Other
sets have the fractional designation i.e. 3/32 or 1/8.

There are lots of rivets out there. There are the old round and
brazier head styles that were both replaced by the universal head and
Boeing has its own protruding head rivet design which is sort of like
the universal head but the head itself is smaller in diameter and
thicker at the edge as if they turned the edge down. All of these
different styles have their own rivet sets to drive them.
